Total |
| Before |
3 u |
8 u |
|
| Change |
+ $49 |
- $6 |
|
| After |
3 u + $49 |
8 u - $6 |
11 u + $43 |
Amount of money Jane and Cindy has is the same in the end.
8 u - 6 = 3 u + 49
8 u - 3 u = 49 + 6
5 u = 55
1 u = 55 ÷ 5 = 11
Amount the girls have in the end
= 3 u + 49 + 8 u - 6
= 11 u + 43
= 11 x 11 + 43
= 121 + 43
= $164
Answer(s): $164
