Bryan |
Before |
3 u |
1 u |
Change |
- 114 |
- 24 |
After |
3 u - 114 |
1 u - 24 |
The amounts that Peter and Bryan had left in the end is the same.
3 u - 114 = 1 u - 24
3 u - 1 u = 114 - 24
2 u = 90
1 u = 90 ÷ 2 = 45
Amount that Bryan had at first
= 1 u
= $45
(a)
Amount that each of them had in the end
= 45 - 24
= $21
Answer(s): (a) $45; (b) $21
