2 u + 46 |
5 u + 4 |
If Cindy received another $6 in the end, she would have the same amount of money as Lucy.
5 u + 4 + 6 = 2 u + 46
5 u + 10 = 2 u + 46
5 u - 2 u = 46 - 10
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that the girls had in the end
= 2 u + 46 + 5 u + 4
= 2 u + 5 u + 46 + 4
= 7 u + 50
= 7 x 12 + 50
= $134
Answer(s): $134
