Mark |
Before |
3 u |
1 u |
Change |
- 128 |
- 32 |
After |
3 u - 128 |
1 u - 32 |
The amounts that Howard and Mark had left in the end is the same.
3 u - 128 = 1 u - 32
3 u - 1 u = 128 - 32
2 u = 96
1 u = 96 ÷ 2 = 48
Amount that Mark had at first
= 1 u
= $48
(a)
Amount that each of them had in the end
= 48 - 32
= $16
Answer(s): (a) $48; (b) $16
