| After |
6 u + 32 |
11 u + 8 |
If Penelope received another $9 in the end, she would have the same amount of money as Zara.
11 u + 8 + 9 = 6 u + 32
11 u + 17 = 6 u + 32
11 u - 6 u = 32 - 17
5 u = 15
1 u = 15 ÷ 5 = 3
Amount that the girls had in the end
= 6 u + 32 + 11 u + 8
= 6 u + 11 u + 32 + 8
= 17 u + 40
= 17 x 3 + 40
= $91
Answer(s): $91
