+ 48 |
+ 7 |
After |
4 u + 48 |
7 u + 7 |
If Sarah received another $2 in the end, she would have the same amount of money as Sabrina.
7 u + 7 + 2 = 4 u + 48
7 u + 9 = 4 u + 48
7 u - 4 u = 48 - 9
3 u = 39
1 u = 39 ÷ 3 = 13
Amount that the girls had in the end
= 4 u + 48 + 7 u + 7
= 4 u + 7 u + 48 + 7
= 11 u + 55
= 11 x 13 + 55
= $198
Answer(s): $198
