4 u |
1 u |
Change |
- 130 |
- 31 |
After |
4 u - 130 |
1 u - 31 |
The amounts that Ahmad and Simon had left in the end is the same.
4 u - 130 = 1 u - 31
4 u - 1 u = 130 - 31
3 u = 99
1 u = 99 ÷ 3 = 33
Amount that Simon had at first
= 1 u
= $33
(a)
Amount that each of them had in the end
= 33 - 31
= $2
Answer(s): (a) $33; (b) $2
