Shiyun and Jack had the same amount of money at first. After Shiyun spent $121 on a wallet and Jack received $29 from his uncle, Jack had 3 times as much as money as Shiyun. How much money did Shiyun have at first?
| |
Shiyun |
Jack |
| Before |
1 u + $121 |
3 u - $29 |
| Change |
- $121 |
+ $29 |
| After |
1 u |
3 u |
Shiyun and Jack had the same amount of money at first.
3 u - 29 = 1 u + 121
3 u - 1 u = 121 + 29
2 u = 150
1 u = 150 ÷ 2 = 75
Amount that Shiyun had at first
= 1 u + 121
= 75 + 121
= $196
Answer(s): $196
