7 u |
|
Change |
+ $46 |
- $6 |
|
After |
3 u + $46 |
7 u - $6 |
10 u + $40 |
Amount of money Wendy and Lynn has is the same in the end.
7 u - 6 = 3 u + 46
7 u - 3 u = 46 + 6
4 u = 52
1 u = 52 ÷ 4 = 13
Amount the girls have in the end
= 3 u + 46 + 7 u - 6
= 10 u + 40
= 10 x 13 + 40
= 130 + 40
= $170
Answer(s): $170
