5 u |
|
Change |
+ $48 |
- $10 |
|
After |
3 u + $48 |
5 u - $10 |
8 u + $38 |
Amount of money Lynn and Sabrina has is the same in the end.
5 u - 10 = 3 u + 48
5 u - 3 u = 48 + 10
2 u = 58
1 u = 58 ÷ 2 = 29
Amount the girls have in the end
= 3 u + 48 + 5 u - 10
= 8 u + 38
= 8 x 29 + 38
= 232 + 38
= $270
Answer(s): $270
