David and Dylan went shopping with the same amount of money. After David spent $57 and Dylan spent $49, Dylan had three times as much money left as David. How much money did each of them bring along for shopping?
| |
David |
Dylan |
| Before |
1 u + $57 |
3 u + $49 |
| Change |
- $57 |
- $49 |
| After |
1 u |
3 u |
David and Dylan brought the same amount for shopping at first.
3 u + 49 = 1 u + 57
3 u - 1 u = 57 - 49
2 u = 8
1 u = 8 ÷ 2 = 4
Amount that each of them brought along for shopping
= 1 u + 57
= 4 + 57
= $61
Answer(s): $61
