Before |
1 u |
4 u |
Change |
+ $189 |
- $189 |
After |
1 u + $189 |
4 u - $189 |
The amounts that Harry and Shiyun had in the end are the same.
4 u - 189 = 1 u + 189
4 u - 1 u = 189 + 189
3 u = 378
1 u = 378 ÷ 3 = 126
Amount that Shiyun had at first
= 1 u
= $126
Amount that Harry had at first
= 4 u
= 4 x 126
= $504
Answer(s): (a) $126; (b) $504
