Justin had 4 times as much money as Xavier. After Xavier's father gave Xavier $36, the amount of money Justin had become $6 less than that of Xavier's. How much did Xavier have in the end?
| |
Xavier |
Justin |
| Before |
1 u |
4 u |
| Change |
+ $36 |
|
| After |
1 u + $36 |
4 u |
The amount that Justin had remains unchanged.
If Justin had another $6, Xavier and Justin would have the same amount in the end.
4 u + 6 = 1 u + 36
4 u - 1 u = 36 - 6
3 u = 36 - 6
3 u = 30
1 u = 30 ÷ 3 = 10
Amount that Xavier had in the end
= 1 u + 36
= 10 + 36
= $46
Answer(s): $46
