Ian |
Tom |
Before |
3 u |
1 u |
Change |
- 127 |
- 39 |
After |
3 u - 127 |
1 u - 39 |
The amounts that Ian and Tom had left in the end is the same.
3 u - 127 = 1 u - 39
3 u - 1 u = 127 - 39
2 u = 88
1 u = 88 ÷ 2 = 44
Amount that Tom had at first
= 1 u
= $44
(a)
Amount that each of them had in the end
= 44 - 39
= $5
Answer(s): (a) $44; (b) $5
