Harry |
Fabian |
Before |
3 u |
1 u |
Change |
- 130 |
- 30 |
After |
3 u - 130 |
1 u - 30 |
The amounts that Harry and Fabian had left in the end is the same.
3 u - 130 = 1 u - 30
3 u - 1 u = 130 - 30
2 u = 100
1 u = 100 ÷ 2 = 50
Amount that Fabian had at first
= 1 u
= $50
(a)
Amount that each of them had in the end
= 50 - 30
= $20
Answer(s): (a) $50; (b) $20
