Alisa bought 3 shirts for $29 each and then spent $15 on lunch. She has $31 left. How much money did she have before?

$133

Step-by-step explanation:

Let x = amount of money she had before she spent any money.

x - 29 - 29 - 29 - 15 = 31

x - 102 = 31

x = 133

She had $133.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
