Join us as we unravel the math behind Colby and Danielle's summer venture and discover the power of combining skills and resources.
Understanding Colby's Income
Colby's income is represented by the linear function f(x) = 3x + 12. Let's break down this equation to fully understand how Colby earns money. In this function, x represents the number of hours Colby works cleaning pools. The coefficient 3 associated with x signifies Colby's hourly rate, meaning he earns $3 for every hour he works. The constant term 12 is particularly interesting; it represents a fixed amount Colby earns regardless of the hours he puts in. This could be interpreted as a base payment or a service fee he charges per pool, irrespective of the time spent cleaning it. Understanding this base amount is crucial as it forms the foundation of Colby's earnings, influencing his total income even before he starts working on an hourly basis. This fixed income component can also be seen as a safety net, ensuring Colby earns a minimum amount even if he has fewer working hours in a particular week.
To illustrate further, if Colby works for 10 hours, we can substitute x with 10 in the equation: f(10) = 3(10) + 12 = 30 + 12 = 42. This calculation shows that Colby would earn $42 for working 10 hours. This example highlights the direct relationship between the hours worked and the income earned, with the base amount of $12 adding to the total. Similarly, if Colby works for 20 hours, his income would be f(20) = 3(20) + 12 = 60 + 12 = 72, resulting in $72 earned. This further reinforces the linear nature of Colby's income model, where each additional hour of work contributes a consistent $3 to his earnings, on top of the initial $12. The linear function f(x) = 3x + 12 provides a clear and predictable way to calculate Colby's income based on the number of hours he dedicates to pool cleaning. This understanding of Colby's income structure is essential for comparing it with Danielle's earnings and for analyzing their combined income when they collaborate. It also provides a foundational understanding for Colby to make informed decisions about his work hours and earning potential, optimizing his summer business for maximum profitability. Analyzing this equation allows us to not only calculate his income but also understand the underlying factors contributing to his earnings, such as his hourly rate and fixed service fee.
Analyzing Danielle's Income
Danielle's income is determined by the function g(x) = 5x + 10. This equation, similar to Colby's, is a linear function where x represents the number of hours Danielle spends cleaning pools. However, the coefficients and constants in Danielle's equation differ, indicating a different income structure. Here, the coefficient 5 associated with x represents Danielle's hourly rate, which is $5 per hour. This is notably higher than Colby's hourly rate of $3, suggesting that Danielle earns more for each hour she works. The constant term 10 represents a fixed amount Danielle earns, similar to Colby's fixed amount, but in this case, it's $10. This could also be interpreted as a base payment or service fee Danielle charges per pool, irrespective of the cleaning time. The fixed amount of $10 contributes to Danielle's total earnings, providing a foundational income regardless of the hours worked. This base payment is slightly lower than Colby's $12, but Danielle's higher hourly rate compensates for this difference.
To illustrate Danielle's income, let's consider a scenario where she works for 10 hours. Substituting x with 10 in her income function, we get g(10) = 5(10) + 10 = 50 + 10 = 60. This means Danielle earns $60 for working 10 hours. Comparing this to Colby's earnings for the same number of hours ($42), it's clear that Danielle earns significantly more due to her higher hourly rate. If Danielle works for 20 hours, her income would be g(20) = 5(20) + 10 = 100 + 10 = 110, resulting in $110 earned. This further demonstrates the impact of Danielle's higher hourly rate on her total income. The linear function g(x) = 5x + 10 provides a straightforward method to calculate Danielle's earnings based on her working hours. Understanding this equation is crucial for comparing her income with Colby's and for analyzing their potential combined earnings. Danielle's higher hourly rate positions her to earn more for the same number of hours worked compared to Colby. This insight is valuable for both Danielle in strategizing her work hours and for comparing their individual earning potentials. The analysis of Danielle's income function reveals the importance of both the hourly rate and the fixed amount in determining overall earnings. Her higher hourly rate, combined with a base payment, makes her income model distinct from Colby's, highlighting the various ways income can be structured in a service-based business.
Combining Colby and Danielle's Efforts
When Colby and Danielle decide to combine their efforts, their individual income functions can be added together to create a new function representing their combined income. This new function, let's call it h(x), is the sum of their individual income functions: h(x) = f(x) + g(x). Substituting the expressions for f(x) and g(x), we get h(x) = (3x + 12) + (5x + 10). Simplifying this equation involves combining like terms: the terms with x and the constant terms. Combining the x terms, 3x + 5x, results in 8x. Combining the constant terms, 12 + 10, gives us 22. Therefore, the combined income function is h(x) = 8x + 22. This new function represents the total income Colby and Danielle earn when they work together, where x still represents the number of hours they work collectively. The coefficient 8 in the combined function indicates that together, they earn $8 per hour. This combined hourly rate is the sum of their individual hourly rates ($3 for Colby and $5 for Danielle). The constant term 22 represents the combined fixed amounts or base payments they receive, which is the sum of Colby's $12 and Danielle's $10.
The combined income function, h(x) = 8x + 22, provides a clear picture of their earning potential when they collaborate. To illustrate this, if Colby and Danielle work together for 10 hours, their combined income would be h(10) = 8(10) + 22 = 80 + 22 = 102. This means they would earn $102 in total for 10 hours of combined work. This example highlights the benefit of combining their efforts, as their combined income is significantly higher than what either of them would earn individually in the same amount of time. If they work for 20 hours together, their combined income would be h(20) = 8(20) + 22 = 160 + 22 = 182, resulting in $182 earned. This demonstrates the linear relationship of their combined income, where each additional hour of work contributes $8 to their total earnings, in addition to the $22 base amount. Analyzing the combined income function reveals the power of collaboration in increasing earning potential. By working together, Colby and Danielle leverage their individual skills and time more effectively, leading to higher overall earnings. This collaborative approach not only increases their income but also allows them to potentially take on more pool cleaning jobs, as they can complete tasks more efficiently as a team. The combined income function h(x) = 8x + 22 serves as a valuable tool for Colby and Danielle to plan their work schedule and estimate their earnings. It also provides a practical example of how combining resources and skills can lead to enhanced financial outcomes. This analysis of their combined efforts underscores the benefits of teamwork and the application of mathematical functions in real-world business scenarios.
Interpreting the Combined Income
Interpreting the combined income function, h(x) = 8x + 22, involves understanding the practical implications of the equation in the context of Colby and Danielle's pool cleaning business. This function tells us how their total earnings are determined when they work together. The key components of this function are the coefficient 8 and the constant term 22, each representing a significant aspect of their collaborative income. As previously mentioned, the coefficient 8 represents their combined hourly rate. This means that for every hour Colby and Danielle work together, they earn a total of $8. This rate is a direct result of summing their individual hourly rates ($3 for Colby and $5 for Danielle). The $8 per hour rate is a critical factor in determining their overall income and reflects the efficiency they achieve by working as a team. The higher hourly rate, compared to Colby's individual rate, highlights the financial advantage of their collaboration.
The constant term 22 represents the combined fixed amount they earn, regardless of the number of hours worked. This fixed amount is the sum of their individual fixed amounts ($12 for Colby and $10 for Danielle). The $22 base payment can be interpreted as a service fee they charge per pool, or it could represent other fixed costs or earnings associated with each job, such as travel expenses or a minimum service charge. This fixed income component ensures that they receive a certain amount for each job, even if the cleaning time is shorter. The constant term adds stability to their income, providing a financial foundation upon which their hourly earnings are built. To further interpret the combined income function, we can analyze different scenarios. For instance, if Colby and Danielle aim to earn a specific amount, such as $200, they can use the function to determine the number of hours they need to work. By setting h(x) = 200, we can solve for x: 200 = 8x + 22. Subtracting 22 from both sides gives 178 = 8x. Dividing by 8, we find x = 22.25. This means they need to work approximately 22.25 hours to earn $200. This type of calculation is valuable for setting financial goals and planning their work schedule accordingly. The combined income function also allows for comparisons between working individually and working together. By comparing their individual income functions with the combined function, Colby and Danielle can assess the financial benefits of their collaboration. This comparison can inform their decision-making process regarding whether to work together on certain jobs or to pursue individual projects. The interpretation of h(x) = 8x + 22 provides a comprehensive understanding of their combined income, allowing Colby and Danielle to make informed decisions about their business strategy and financial goals. It also serves as a practical example of how linear functions can be used to model and analyze real-world financial scenarios, emphasizing the importance of mathematical literacy in business and entrepreneurship.
