David |
Before |
4 u |
1 u |
Change |
- 118 |
- 28 |
After |
4 u - 118 |
1 u - 28 |
The amounts that Ken and David had left in the end is the same.
4 u - 118 = 1 u - 28
4 u - 1 u = 118 - 28
3 u = 90
1 u = 90 ÷ 3 = 30
Amount that David had at first
= 1 u
= $30
(a)
Amount that each of them had in the end
= 30 - 28
= $2
Answer(s): (a) $30; (b) $2
