Julian |
Before |
3 u |
1 u |
Change |
- 129 |
- 25 |
After |
3 u - 129 |
1 u - 25 |
The amounts that Vaidev and Julian had left in the end is the same.
3 u - 129 = 1 u - 25
3 u - 1 u = 129 - 25
2 u = 104
1 u = 104 ÷ 2 = 52
Amount that Julian had at first
= 1 u
= $52
(a)
Amount that each of them had in the end
= 52 - 25
= $27
Answer(s): (a) $52; (b) $27
