5.50h=m

Answer: Crystal would earn $20.625 by working 3 hours and 45 minutes.

Explanation:

Since we have given that

Cost per hour for mowing lawns = $5.50

Let h be the number of hours.

Let the amount of money be 'm'.

So, the equation would be


m=5.50h

If number of hours = 3 hours 45 minutes =
3(45)/(60)=3(3)/(4)=(15)/(4)

So, Amount of money earned by Crystal would be


m=5.50* (15)/(4)\\\\m=\$20.625

Hence, Crystal would earn $20.625 by working 3 hours and 45 minutes.
