Daniel |
Glen |
Before |
4 u |
1 u |
Change |
- 115 |
- 22 |
After |
4 u - 115 |
1 u - 22 |
The amounts that Daniel and Glen had left in the end is the same.
4 u - 115 = 1 u - 22
4 u - 1 u = 115 - 22
3 u = 93
1 u = 93 ÷ 3 = 31
Amount that Glen had at first
= 1 u
= $31
(a)
Amount that each of them had in the end
= 31 - 22
= $9
Answer(s): (a) $31; (b) $9
