Ivan had 3 times as much money as Charlie. After Charlie's father gave Charlie $37, the amount of money Ivan had become $5 less than that of Charlie's. How much did Charlie have in the end?
| |
Charlie |
Ivan |
| Before |
1 u |
3 u |
| Change |
+ $37 |
|
| After |
1 u + $37 |
3 u |
The amount that Ivan had remains unchanged.
If Ivan had another $5, Charlie and Ivan would have the same amount in the end.
3 u + 5 = 1 u + 37
3 u - 1 u = 37 - 5
2 u = 37 - 5
2 u = 32
1 u = 32 ÷ 2 = 16
Amount that Charlie had in the end
= 1 u + 37
= 16 + 37
= $53
Answer(s): $53
