Peter and Justin went shopping with the same amount of money. After Peter spent $79 and Justin spent $47, Justin had five times as much money left as Peter. How much money did each of them bring along for shopping?

Peter |
Justin |
| Before |
1 u + $79 |
5 u + $47 |
| Change |
- $79 |
- $47 |
| After |
1 u |
5 u |
Peter and Justin brought the same amount for shopping at first.
5 u + 47 = 1 u + 79
5 u - 1 u = 79 - 47
4 u = 32
1 u = 32 ÷ 4 = 8
Amount that each of them brought along for shopping
= 1 u + 79
= 8 + 79
= $87
Answer(s): $87
