Question

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

Answer 1

she had 133$

Explanation:

Multiply 29$ by the amount of shirts and get 87$

then add 31$, the 15$ she spent on lunch, and add the 87$ and get 133$.

Answer 2

$133

Explanation:

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

x - 29 - 29 - 29 - 15 = 31

x - 102 = 31

x = 133

Answer: She had $133.
