7 u |
|
Change |
+ $34 |
- $10 |
|
After |
3 u + $34 |
7 u - $10 |
10 u + $24 |
Amount of money Tiffany and Fanny has is the same in the end.
7 u - 10 = 3 u + 34
7 u - 3 u = 34 + 10
4 u = 44
1 u = 44 ÷ 4 = 11
Amount the girls have in the end
= 3 u + 34 + 7 u - 10
= 10 u + 24
= 10 x 11 + 24
= 110 + 24
= $134
Answer(s): $134
