Jack |
Howard |
Before |
3 u |
1 u |
Change |
- 121 |
- 25 |
After |
3 u - 121 |
1 u - 25 |
The amounts that Jack and Howard had left in the end is the same.
3 u - 121 = 1 u - 25
3 u - 1 u = 121 - 25
2 u = 96
1 u = 96 ÷ 2 = 48
Amount that Howard had at first
= 1 u
= $48
(a)
Amount that each of them had in the end
= 48 - 25
= $23
Answer(s): (a) $48; (b) $23
