Ethan and Seth went shopping with the same amount of money. After Ethan spent $105 and Seth spent $91, Seth had three times as much money left as Ethan. How much money did each of them bring along for shopping?
| |
Ethan |
Seth |
| Before |
1 u + $105 |
3 u + $91 |
| Change |
- $105 |
- $91 |
| After |
1 u |
3 u |
Ethan and Seth brought the same amount for shopping at first.
3 u + 91 = 1 u + 105
3 u - 1 u = 105 - 91
2 u = 14
1 u = 14 ÷ 2 = 7
Amount that each of them brought along for shopping
= 1 u + 105
= 7 + 105
= $112
Answer(s): $112
