Billy and Ryan went shopping with the same amount of money. After Billy spent $109 and Ryan spent $99, Ryan had three times as much money left as Billy. How much money did each of them bring along for shopping?
| |
Billy |
Ryan |
| Before |
1 u + $109 |
3 u + $99 |
| Change |
- $109 |
- $99 |
| After |
1 u |
3 u |
Billy and Ryan brought the same amount for shopping at first.
3 u + 99 = 1 u + 109
3 u - 1 u = 109 - 99
2 u = 10
1 u = 10 ÷ 2 = 5
Amount that each of them brought along for shopping
= 1 u + 109
= 5 + 109
= $114
Answer(s): $114
