5 u |

Change |
+ $48 |
- $12 |
|
After |
1 u + $48 |
5 u - $12 |
6 u + $36 |
Amount of money Joelle and Tiffany has is the same in the end.
5 u - 12 = 1 u + 48
5 u - 1 u = 48 + 12
4 u = 60
1 u = 60 ÷ 4 = 15
Amount the girls have in the end
= 1 u + 48 + 5 u - 12
= 6 u + 36
= 6 x 15 + 36
= 90 + 36
= $126
Answer(s): $126
