1 u |
5 u |
|
Change |
+ $25 |
- $11 |
|
After |
1 u + $25 |
5 u - $11 |
6 u + $14 |
Amount of money Gwen and Jaslyn has is the same in the end.
5 u - 11 = 1 u + 25
5 u - 1 u = 25 + 11
4 u = 36
1 u = 36 ÷ 4 = 9
Amount the girls have in the end
= 1 u + 25 + 5 u - 11
= 6 u + 14
= 6 x 9 + 14
= 54 + 14
= $68
Answer(s): $68
