Elijah |
Carl |
Before |
3 u |
1 u |
Change |
- 121 |
- 35 |
After |
3 u - 121 |
1 u - 35 |
The amounts that Elijah and Carl had left in the end is the same.
3 u - 121 = 1 u - 35
3 u - 1 u = 121 - 35
2 u = 86
1 u = 86 ÷ 2 = 43
Amount that Carl had at first
= 1 u
= $43
(a)
Amount that each of them had in the end
= 43 - 35
= $8
Answer(s): (a) $43; (b) $8
