Tina |
Julian |
Before |
1 u |
4 u |
Change |
+ $126 |
- $126 |
After |
1 u + $126 |
4 u - $126 |
The amounts that Julian and Tina had in the end are the same.
4 u - 126 = 1 u + 126
4 u - 1 u = 126 + 126
3 u = 252
1 u = 252 ÷ 3 = 84
Amount that Tina had at first
= 1 u
= $84
Amount that Julian had at first
= 4 u
= 4 x 84
= $336
Answer(s): (a) $84; (b) $336
