Liam had 4 times as much money as Oliver. After Oliver's father gave Oliver $39, the amount of money Liam had become $6 less than that of Oliver's. How much did Oliver have in the end?
| |
Oliver |
Liam |
| Before |
1 u |
4 u |
| Change |
+ $39 |
|
| After |
1 u + $39 |
4 u |
The amount that Liam had remains unchanged.
If Liam had another $6, Oliver and Liam would have the same amount in the end.
4 u + 6 = 1 u + 39
4 u - 1 u = 39 - 6
3 u = 39 - 6
3 u = 33
1 u = 33 ÷ 3 = 11
Amount that Oliver had in the end
= 1 u + 39
= 11 + 39
= $50
Answer(s): $50
