8 u + 7 |
If Shannon received another $7 in the end, she would have the same amount of money as Jane.
8 u + 7 + 7 = 5 u + 35
8 u + 14 = 5 u + 35
8 u - 5 u = 35 - 14
3 u = 21
1 u = 21 ÷ 3 = 7
Amount that the girls had in the end
= 5 u + 35 + 8 u + 7
= 5 u + 8 u + 35 + 7
= 13 u + 42
= 13 x 7 + 42
= $133
Answer(s): $133
