Before |
1 u |
7 u |
|
Change |
+ $29 |
- $7 |
|
After |
1 u + $29 |
7 u - $7 |
8 u + $22 |
Amount of money Gabby and Jaslyn has is the same in the end.
7 u - 7 = 1 u + 29
7 u - 1 u = 29 + 7
6 u = 36
1 u = 36 ÷ 6 = 6
Amount the girls have in the end
= 1 u + 29 + 7 u - 7
= 8 u + 22
= 8 x 6 + 22
= 48 + 22
= $70
Answer(s): $70
