Your profit for mowing lawns this week is $24. You are paid $8 per hour and you paid $40 for gas for the lawn mower. How many hours did you work this week?
We know profit from the equation below:
Revenue - Cost = Profit
We're given Profit as 42, so we have:
Revenue - Cost = 42
Let hours worked be h. We have revenue as:
Revenue = 8h
Cost = 40, so we plug these into profit to get:
8h - 40 = 42
To solve this equation for h, we plug this equation into our math engine and get:
h = 10.25
