Tom |
Caden |
Before |
3 u |
1 u |
Change |
- 128 |
- 36 |
After |
3 u - 128 |
1 u - 36 |
The amounts that Tom and Caden had left in the end is the same.
3 u - 128 = 1 u - 36
3 u - 1 u = 128 - 36
2 u = 92
1 u = 92 ÷ 2 = 46
Amount that Caden had at first
= 1 u
= $46
(a)
Amount that each of them had in the end
= 46 - 36
= $10
Answer(s): (a) $46; (b) $10
