7 u |
|
Change |
+ $44 |
- $8 |
|
After |
3 u + $44 |
7 u - $8 |
10 u + $36 |
Amount of money Vanessa and Lynn has is the same in the end.
7 u - 8 = 3 u + 44
7 u - 3 u = 44 + 8
4 u = 52
1 u = 52 ÷ 4 = 13
Amount the girls have in the end
= 3 u + 44 + 7 u - 8
= 10 u + 36
= 10 x 13 + 36
= 130 + 36
= $166
Answer(s): $166
