Final answer:
To calculate William's earnings, we need his hourly rate and the number of hours he worked washing a car and mowing a lawn. With that information, we can use the formula Total earnings = Hourly rate x Total hours worked for all tasks.
Step-by-step explanation:
To determine how much money William makes, we would need to know William's hourly rate and the total amount of hours worked washing a car and mowing a lawn, in addition to the 1/2 hour spent cleaning a house. Without these details, we cannot calculate his total earnings for the weekend. It's important to note that we need a specific number of hours for the car washing and lawn mowing tasks and William's hourly rate to proceed with the calculation. For example, if William's hourly rate is $10 and he spent 1 hour washing the car and 1 hour mowing the lawn, his total earnings would be calculated as:
Total earnings = (Hourly rate x Hours worked cleaning) + (Hourly rate x Hours worked washing a car) + (Hourly rate x Hours worked mowing a lawn)
In this example, Total earnings = ($10 x 0.5) + ($10 x 1) + ($10 x 1) = $5 + $10 + $10 = $25.
Example Clarification:
In the provided reference information, we have examples of different economic situations such as the effect of a guaranteed income, Aaron's Word Processing Service's pricing structure, and determining the relative price of goods. However, these examples are separate from the question about William's earnings as they are specific scenarios given to illustrate different economic concepts. To answer the question about William's earnings, we would need the missing details regarding his hourly rate and hours worked.
