Japheth had 3 times as much money as Jack. After Jack's father gave Jack $24, the amount of money Japheth had become $4 less than that of Jack's. How much did Jack have in the end?

Jack |
Japheth |
| Before |
1 u |
3 u |
| Change |
+ $24 |
|
| After |
1 u + $24 |
3 u |
The amount that Japheth had remains unchanged.
If Japheth had another $4, Jack and Japheth would have the same amount in the end.
3 u + 4 = 1 u + 24
3 u - 1 u = 24 - 4
2 u = 24 - 4
2 u = 20
1 u = 20 ÷ 2 = 10
Amount that Jack had in the end
= 1 u + 24
= 10 + 24
= $34
Answer(s): $34
