Before |
3 u |
1 u |
Change |
- 116 |
- 38 |
After |
3 u - 116 |
1 u - 38 |
The amounts that Fred and Billy had left in the end is the same.
3 u - 116 = 1 u - 38
3 u - 1 u = 116 - 38
2 u = 78
1 u = 78 ÷ 2 = 39
Amount that Billy had at first
= 1 u
= $39
(a)
Amount that each of them had in the end
= 39 - 38
= $1
Answer(s): (a) $39; (b) $1
