| Before |
3 u |
8 u |
|
| Change |
+ $43 |
- $7 |
|
| After |
3 u + $43 |
8 u - $7 |
11 u + $36 |
Amount of money Gem and Shannon has is the same in the end.
8 u - 7 = 3 u + 43
8 u - 3 u = 43 + 7
5 u = 50
1 u = 50 ÷ 5 = 10
Amount the girls have in the end
= 3 u + 43 + 8 u - 7
= 11 u + 36
= 11 x 10 + 36
= 110 + 36
= $146
Answer(s): $146
