Elijah |
Oliver |
Before |
3 u |
1 u |
Change |
- 126 |
- 40 |
After |
3 u - 126 |
1 u - 40 |
The amounts that Elijah and Oliver had left in the end is the same.
3 u - 126 = 1 u - 40
3 u - 1 u = 126 - 40
2 u = 86
1 u = 86 ÷ 2 = 43
Amount that Oliver had at first
= 1 u
= $43
(a)
Amount that each of them had in the end
= 43 - 40
= $3
Answer(s): (a) $43; (b) $3
