Ethan |
Before |
3 u |
1 u |
Change |
- 128 |
- 28 |
After |
3 u - 128 |
1 u - 28 |
The amounts that Dylan and Ethan had left in the end is the same.
3 u - 128 = 1 u - 28
3 u - 1 u = 128 - 28
2 u = 100
1 u = 100 ÷ 2 = 50
Amount that Ethan had at first
= 1 u
= $50
(a)
Amount that each of them had in the end
= 50 - 28
= $22
Answer(s): (a) $50; (b) $22
