Paul |
Before |
3 u |
1 u |
Change |
- 123 |
- 39 |
After |
3 u - 123 |
1 u - 39 |
The amounts that Jenson and Paul had left in the end is the same.
3 u - 123 = 1 u - 39
3 u - 1 u = 123 - 39
2 u = 84
1 u = 84 ÷ 2 = 42
Amount that Paul had at first
= 1 u
= $42
(a)
Amount that each of them had in the end
= 42 - 39
= $3
Answer(s): (a) $42; (b) $3
