Tom had 4 times as much money as Ken. After Ken's father gave Ken $24, the amount of money Tom had become $3 less than that of Ken's. How much did Ken have in the end?
| |
Ken |
Tom |
| Before |
1 u |
4 u |
| Change |
+ $24 |
|
| After |
1 u + $24 |
4 u |
The amount that Tom had remains unchanged.
If Tom had another $3, Ken and Tom would have the same amount in the end.
4 u + 3 = 1 u + 24
4 u - 1 u = 24 - 3
3 u = 24 - 3
3 u = 21
1 u = 21 ÷ 3 = 7
Amount that Ken had in the end
= 1 u + 24
= 7 + 24
= $31
Answer(s): $31
