Zeph |
Before |
3 u |
1 u |
Change |
- 111 |
- 27 |
After |
3 u - 111 |
1 u - 27 |
The amounts that Zane and Zeph had left in the end is the same.
3 u - 111 = 1 u - 27
3 u - 1 u = 111 - 27
2 u = 84
1 u = 84 ÷ 2 = 42
Amount that Zeph had at first
= 1 u
= $42
(a)
Amount that each of them had in the end
= 42 - 27
= $15
Answer(s): (a) $42; (b) $15
