Luis |
Before |
3 u |
1 u |
Change |
- 122 |
- 24 |
After |
3 u - 122 |
1 u - 24 |
The amounts that Glen and Luis had left in the end is the same.
3 u - 122 = 1 u - 24
3 u - 1 u = 122 - 24
2 u = 98
1 u = 98 ÷ 2 = 49
Amount that Luis had at first
= 1 u
= $49
(a)
Amount that each of them had in the end
= 49 - 24
= $25
Answer(s): (a) $49; (b) $25
