| After |
5 u + 45 |
7 u + 9 |
If Hazel received another $8 in the end, she would have the same amount of money as Kylie.
7 u + 9 + 8 = 5 u + 45
7 u + 17 = 5 u + 45
7 u - 5 u = 45 - 17
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that the girls had in the end
= 5 u + 45 + 7 u + 9
= 5 u + 7 u + 45 + 9
= 12 u + 54
= 12 x 14 + 54
= $222
Answer(s): $222
