Billy and Julian went shopping with the same amount of money. After Billy spent $72 and Julian spent $36, Julian had four times as much money left as Billy. How much money did each of them bring along for shopping?
| |
Billy |
Julian |
| Before |
1 u + $72 |
4 u + $36 |
| Change |
- $72 |
- $36 |
| After |
1 u |
4 u |
Billy and Julian brought the same amount for shopping at first.
4 u + 36 = 1 u + 72
4 u - 1 u = 72 - 36
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that each of them brought along for shopping
= 1 u + 72
= 12 + 72
= $84
Answer(s): $84
