Cody |
Before |
3 u |
1 u |
Change |
- 113 |
- 33 |
After |
3 u - 113 |
1 u - 33 |
The amounts that Jack and Cody had left in the end is the same.
3 u - 113 = 1 u - 33
3 u - 1 u = 113 - 33
2 u = 80
1 u = 80 ÷ 2 = 40
Amount that Cody had at first
= 1 u
= $40
(a)
Amount that each of them had in the end
= 40 - 33
= $7
Answer(s): (a) $40; (b) $7
