Before |
1 u |
3 u |
Change |
+ $141 |
- $141 |
After |
1 u + $141 |
3 u - $141 |
The amounts that Harry and Min had in the end are the same.
3 u - 141 = 1 u + 141
3 u - 1 u = 141 + 141
2 u = 282
1 u = 282 ÷ 2 = 141
Amount that Min had at first
= 1 u
= $141
Amount that Harry had at first
= 3 u
= 3 x 141
= $423
Answer(s): (a) $141; (b) $423
