a. Choose the rule that describes how the amount of money m earned is a function
of the number of hours h spent mowing lawns.
b. How much does Crystal earn if she works 3 hours and 45 minutes?

Answer 1

The solution to the problem is as follows:

Let m be the rate Crystal earns per hour on mowing the lawns.

m = 5.5h

Since:

rate = quantity / time

quantity (earnings) = 5.5 *3.75 = $20 and 62.5 cents

Therefore, she earns $20 and 62.5 cents in 3 hours and 45 minutes.
