Nick |
Oliver |
Before |
3 u |
1 u |
Change |
- 129 |
- 33 |
After |
3 u - 129 |
1 u - 33 |
The amounts that Nick and Oliver had left in the end is the same.
3 u - 129 = 1 u - 33
3 u - 1 u = 129 - 33
2 u = 96
1 u = 96 ÷ 2 = 48
Amount that Oliver had at first
= 1 u
= $48
(a)
Amount that each of them had in the end
= 48 - 33
= $15
Answer(s): (a) $48; (b) $15
