| After |
9 u + 40 |
11 u + 2 |
If Jen received another $6 in the end, she would have the same amount of money as Ivory.
11 u + 2 + 6 = 9 u + 40
11 u + 8 = 9 u + 40
11 u - 9 u = 40 - 8
2 u = 32
1 u = 32 ÷ 2 = 16
Amount that the girls had in the end
= 9 u + 40 + 11 u + 2
= 9 u + 11 u + 40 + 2
= 20 u + 42
= 20 x 16 + 42
= $362
Answer(s): $362
