After |
4 u + 49 |
7 u + 8 |
If Gabby received another $5 in the end, she would have the same amount of money as Lucy.
7 u + 8 + 5 = 4 u + 49
7 u + 13 = 4 u + 49
7 u - 4 u = 49 - 13
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that the girls had in the end
= 4 u + 49 + 7 u + 8
= 4 u + 7 u + 49 + 8
= 11 u + 57
= 11 x 12 + 57
= $189
Answer(s): $189
