Zane had 3 times as much money as Zeph. After Zeph's father gave Zeph $39, the amount of money Zane had become $3 less than that of Zeph's. How much did Zeph have in the end?

Zane |
| Before |
1 u |
3 u |
| Change |
+ $39 |
|
| After |
1 u + $39 |
3 u |
The amount that Zane had remains unchanged.
If Zane had another $3, Zeph and Zane would have the same amount in the end.
3 u + 3 = 1 u + 39
3 u - 1 u = 39 - 3
2 u = 39 - 3
2 u = 36
1 u = 36 ÷ 2 = 18
Amount that Zeph had in the end
= 1 u + 39
= 18 + 39
= $57
Answer(s): $57
