Bobby had 4 times as much money as Sam. After Sam's father gave Sam $24, the amount of money Bobby had become $6 less than that of Sam's. How much did Sam have in the end?

Sam |
Bobby |
| Before |
1 u |
4 u |
| Change |
+ $24 |
|
| After |
1 u + $24 |
4 u |
The amount that Bobby had remains unchanged.
If Bobby had another $6, Sam and Bobby would have the same amount in the end.
4 u + 6 = 1 u + 24
4 u - 1 u = 24 - 6
3 u = 24 - 6
3 u = 18
1 u = 18 ÷ 3 = 6
Amount that Sam had in the end
= 1 u + 24
= 6 + 24
= $30
Answer(s): $30
