| After |
3 u + 42 |
5 u + 6 |
If Rachel received another $4 in the end, she would have the same amount of money as Shannon.
5 u + 6 + 4 = 3 u + 42
5 u + 10 = 3 u + 42
5 u - 3 u = 42 - 10
2 u = 32
1 u = 32 ÷ 2 = 16
Amount that the girls had in the end
= 3 u + 42 + 5 u + 6
= 3 u + 5 u + 42 + 6
= 8 u + 48
= 8 x 16 + 48
= $176
Answer(s): $176
