8 u |
|
Change |
+ $35 |
- $10 |
|
After |
3 u + $35 |
8 u - $10 |
11 u + $25 |
Amount of money Kylie and Fiona has is the same in the end.
8 u - 10 = 3 u + 35
8 u - 3 u = 35 + 10
5 u = 45
1 u = 45 ÷ 5 = 9
Amount the girls have in the end
= 3 u + 35 + 8 u - 10
= 11 u + 25
= 11 x 9 + 25
= 99 + 25
= $124
Answer(s): $124
