Archie |
Zane |
Before |
3 u |
1 u |
Change |
- 127 |
- 29 |
After |
3 u - 127 |
1 u - 29 |
The amounts that Archie and Zane had left in the end is the same.
3 u - 127 = 1 u - 29
3 u - 1 u = 127 - 29
2 u = 98
1 u = 98 ÷ 2 = 49
Amount that Zane had at first
= 1 u
= $49
(a)
Amount that each of them had in the end
= 49 - 29
= $20
Answer(s): (a) $49; (b) $20
