Before |
1 u |
3 u |
Change |
+ $168 |
- $168 |
After |
1 u + $168 |
3 u - $168 |
The amounts that Albert and Fiona had in the end are the same.
3 u - 168 = 1 u + 168
3 u - 1 u = 168 + 168
2 u = 336
1 u = 336 ÷ 2 = 168
Amount that Fiona had at first
= 1 u
= $168
Amount that Albert had at first
= 3 u
= 3 x 168
= $504
Answer(s): (a) $168; (b) $504
