Final answer:
The student's question involves creating an equation to represent the total cost of renting scuba equipment based on the number of rental hours, analogous to calculating service rates or the cost of running electrical equipment. The solution is a linear equation where the total cost includes a fixed charge plus a variable rate multiplied by the number of hours.
Step-by-step explanation:
The equation representing the total cost to rent scuba equipment based on the number of hours rented is given by c = 27 + 10h, where c is the cost in dollars and h is the number of hours rented. If we compare this to Aaron's Word Processing Service, where the total cost, y, is y = 31.50 + 32x and x is the number of hours of work, we can see a similar structure. Just like in the word processing example, in the scuba equipment rental, 27 dollars represents a one-time upfront fee and 10 dollars per hour is the variable rate based on the duration of rental.
For an analogy in a different context, let's consider the cost of running electrical equipment. The cost is calculated by the formula E = Pt, where E is the energy consumed in kilowatt hours (kWh), P is the power consumption rate in kilowatts (kW), and t is the time in hours. Similarly, the cost of equipment rental is determined both by a fixed rate and a rate that depends on the rental duration.
Understanding linear equations and how to formulate them based on a given scenario is crucial in both business and personal finance planning. For example, knowing how to determine the total cost of producing a product given the labor hours and hourly wage rates can help make informed decisions about resource allocation and budgeting.
