Owen |
Zane |
Before |
3 u |
1 u |
Change |
- 110 |
- 20 |
After |
3 u - 110 |
1 u - 20 |
The amounts that Owen and Zane had left in the end is the same.
3 u - 110 = 1 u - 20
3 u - 1 u = 110 - 20
2 u = 90
1 u = 90 ÷ 2 = 45
Amount that Zane had at first
= 1 u
= $45
(a)
Amount that each of them had in the end
= 45 - 20
= $25
Answer(s): (a) $45; (b) $25
