Total |
Before |
3 u |
8 u |
|
Change |
+ $34 |
- $6 |
|
After |
3 u + $34 |
8 u - $6 |
11 u + $28 |
Amount of money Risa and Joelle has is the same in the end.
8 u - 6 = 3 u + 34
8 u - 3 u = 34 + 6
5 u = 40
1 u = 40 ÷ 5 = 8
Amount the girls have in the end
= 3 u + 34 + 8 u - 6
= 11 u + 28
= 11 x 8 + 28
= 88 + 28
= $116
Answer(s): $116
