| After |
6 u + 43 |
11 u + 4 |
If Cindy received another $4 in the end, she would have the same amount of money as Tina.
11 u + 4 + 4 = 6 u + 43
11 u + 8 = 6 u + 43
11 u - 6 u = 43 - 8
5 u = 35
1 u = 35 ÷ 5 = 7
Amount that the girls had in the end
= 6 u + 43 + 11 u + 4
= 6 u + 11 u + 43 + 4
= 17 u + 47
= 17 x 7 + 47
= $166
Answer(s): $166
