| Before |
3 u |
10 u |
|
| Change |
+ $41 |
- $8 |
|
| After |
3 u + $41 |
10 u - $8 |
13 u + $33 |
Amount of money Cindy and Gillian has is the same in the end.
10 u - 8 = 3 u + 41
10 u - 3 u = 41 + 8
7 u = 49
1 u = 49 ÷ 7 = 7
Amount the girls have in the end
= 3 u + 41 + 10 u - 8
= 13 u + 33
= 13 x 7 + 33
= 91 + 33
= $124
Answer(s): $124
