| After |
5 u + 41 |
9 u + 7 |
If Olivia received another $2 in the end, she would have the same amount of money as Jean.
9 u + 7 + 2 = 5 u + 41
9 u + 9 = 5 u + 41
9 u - 5 u = 41 - 9
4 u = 32
1 u = 32 ÷ 4 = 8
Amount that the girls had in the end
= 5 u + 41 + 9 u + 7
= 5 u + 9 u + 41 + 7
= 14 u + 48
= 14 x 8 + 48
= $160
Answer(s): $160
