Total |
| Before |
3 u |
5 u |
|
| Change |
+ $35 |
- $7 |
|
| After |
3 u + $35 |
5 u - $7 |
8 u + $28 |
Amount of money Gabby and Sarah has is the same in the end.
5 u - 7 = 3 u + 35
5 u - 3 u = 35 + 7
2 u = 42
1 u = 42 ÷ 2 = 21
Amount the girls have in the end
= 3 u + 35 + 5 u - 7
= 8 u + 28
= 8 x 21 + 28
= 168 + 28
= $196
Answer(s): $196
