Seth |
Vincent |
Before |
3 u |
1 u |
Change |
- 119 |
- 39 |
After |
3 u - 119 |
1 u - 39 |
The amounts that Seth and Vincent had left in the end is the same.
3 u - 119 = 1 u - 39
3 u - 1 u = 119 - 39
2 u = 80
1 u = 80 ÷ 2 = 40
Amount that Vincent had at first
= 1 u
= $40
(a)
Amount that each of them had in the end
= 40 - 39
= $1
Answer(s): (a) $40; (b) $1
