| After |
3 u + 45 |
7 u + 3 |
If Raeann received another $2 in the end, she would have the same amount of money as Jen.
7 u + 3 + 2 = 3 u + 45
7 u + 5 = 3 u + 45
7 u - 3 u = 45 - 5
4 u = 40
1 u = 40 ÷ 4 = 10
Amount that the girls had in the end
= 3 u + 45 + 7 u + 3
= 3 u + 7 u + 45 + 3
= 10 u + 48
= 10 x 10 + 48
= $148
Answer(s): $148
