3 u + 31 |
8 u + 9 |
If Lynn received another $2 in the end, she would have the same amount of money as Ivory.
8 u + 9 + 2 = 3 u + 31
8 u + 11 = 3 u + 31
8 u - 3 u = 31 - 11
5 u = 20
1 u = 20 ÷ 5 = 4
Amount that the girls had in the end
= 3 u + 31 + 8 u + 9
= 3 u + 8 u + 31 + 9
= 11 u + 40
= 11 x 4 + 40
= $84
Answer(s): $84
