8 u |
|
Change |
+ $26 |
- $9 |
|
After |
1 u + $26 |
8 u - $9 |
9 u + $17 |
Amount of money Rachel and Olivia has is the same in the end.
8 u - 9 = 1 u + 26
8 u - 1 u = 26 + 9
7 u = 35
1 u = 35 ÷ 7 = 5
Amount the girls have in the end
= 1 u + 26 + 8 u - 9
= 9 u + 17
= 9 x 5 + 17
= 45 + 17
= $62
Answer(s): $62
