| After |
3 u + 44 |
8 u + 2 |
If Lucy received another $7 in the end, she would have the same amount of money as Jean.
8 u + 2 + 7 = 3 u + 44
8 u + 9 = 3 u + 44
8 u - 3 u = 44 - 9
5 u = 35
1 u = 35 ÷ 5 = 7
Amount that the girls had in the end
= 3 u + 44 + 8 u + 2
= 3 u + 8 u + 44 + 2
= 11 u + 46
= 11 x 7 + 46
= $123
Answer(s): $123
