After |
6 u + 41 |
11 u + 3 |
If Fanny received another $3 in the end, she would have the same amount of money as Betty.
11 u + 3 + 3 = 6 u + 41
11 u + 6 = 6 u + 41
11 u - 6 u = 41 - 6
5 u = 35
1 u = 35 ÷ 5 = 7
Amount that the girls had in the end
= 6 u + 41 + 11 u + 3
= 6 u + 11 u + 41 + 3
= 17 u + 44
= 17 x 7 + 44
= $163
Answer(s): $163
