Justin |
John |
Before |
3 u |
1 u |
Change |
- 126 |
- 28 |
After |
3 u - 126 |
1 u - 28 |
The amounts that Justin and John had left in the end is the same.
3 u - 126 = 1 u - 28
3 u - 1 u = 126 - 28
2 u = 98
1 u = 98 ÷ 2 = 49
Amount that John had at first
= 1 u
= $49
(a)
Amount that each of them had in the end
= 49 - 28
= $21
Answer(s): (a) $49; (b) $21
