Zeph |
Before |
4 u |
1 u |
Change |
- 129 |
- 27 |
After |
4 u - 129 |
1 u - 27 |
The amounts that Albert and Zeph had left in the end is the same.
4 u - 129 = 1 u - 27
4 u - 1 u = 129 - 27
3 u = 102
1 u = 102 ÷ 3 = 34
Amount that Zeph had at first
= 1 u
= $34
(a)
Amount that each of them had in the end
= 34 - 27
= $7
Answer(s): (a) $34; (b) $7
