At a pizza restaurant, Mason earns $7.25 per hour to deliver pizzas and $9.00 per hour to make pizzas. One week he earned total of $288.75. During that week he made pizzas for 20 hours. The equation 7.25h + 9(20) = 288.75 could be used to find h, the number of hours he spent delivering pizzas. How many hours that he spent delivering pizzas?

7.25h + 9(20) = 288.75

Multiply 9 by 20:

7.25h + 180 = 288.75

Subtract 180 from both sides:

7.25h = 108.75

Divide both sides by 7.25

h = 108.75 / 7.25

h = 15

He spent 15 hours delivering pizzas.
