| After |
5 u + 40 |
9 u + 7 |
If Natalie received another $5 in the end, she would have the same amount of money as Joelle.
9 u + 7 + 5 = 5 u + 40
9 u + 12 = 5 u + 40
9 u - 5 u = 40 - 12
4 u = 28
1 u = 28 ÷ 4 = 7
Amount that the girls had in the end
= 5 u + 40 + 9 u + 7
= 5 u + 9 u + 40 + 7
= 14 u + 47
= 14 x 7 + 47
= $145
Answer(s): $145
