Glen |
Liam |
Before |
3 u |
1 u |
Change |
- 120 |
- 22 |
After |
3 u - 120 |
1 u - 22 |
The amounts that Glen and Liam had left in the end is the same.
3 u - 120 = 1 u - 22
3 u - 1 u = 120 - 22
2 u = 98
1 u = 98 ÷ 2 = 49
Amount that Liam had at first
= 1 u
= $49
(a)
Amount that each of them had in the end
= 49 - 22
= $27
Answer(s): (a) $49; (b) $27
