Reggie |
Before |
3 u |
1 u |
Change |
- 128 |
- 38 |
After |
3 u - 128 |
1 u - 38 |
The amounts that Howard and Reggie had left in the end is the same.
3 u - 128 = 1 u - 38
3 u - 1 u = 128 - 38
2 u = 90
1 u = 90 ÷ 2 = 45
Amount that Reggie had at first
= 1 u
= $45
(a)
Amount that each of them had in the end
= 45 - 38
= $7
Answer(s): (a) $45; (b) $7
