4 u + 48 |
7 u + 3 |
If Lynn received another $3 in the end, she would have the same amount of money as Shannon.
7 u + 3 + 3 = 4 u + 48
7 u + 6 = 4 u + 48
7 u - 4 u = 48 - 6
3 u = 42
1 u = 42 ÷ 3 = 14
Amount that the girls had in the end
= 4 u + 48 + 7 u + 3
= 4 u + 7 u + 48 + 3
= 11 u + 51
= 11 x 14 + 51
= $205
Answer(s): $205
