Total |
Before |
3 u |
7 u |
|
Change |
+ $29 |
- $7 |
|
After |
3 u + $29 |
7 u - $7 |
10 u + $22 |
Amount of money Jade and Julie has is the same in the end.
7 u - 7 = 3 u + 29
7 u - 3 u = 29 + 7
4 u = 36
1 u = 36 ÷ 4 = 9
Amount the girls have in the end
= 3 u + 29 + 7 u - 7
= 10 u + 22
= 10 x 9 + 22
= 90 + 22
= $112
Answer(s): $112
