47 as much money as Yen. Esther received another $35 from her uncle and Yen received $9 from her aunt. In the end, Esther had $5 more than Yen. How much did the girls have altogether in the end?

Change |
+ 35 |
+ 9 |
After |
4 u + 35 |
7 u + 9 |
If Yen received another $5 in the end, she would have the same amount of money as Esther.
7 u + 9 + 5 = 4 u + 35
7 u + 14 = 4 u + 35
7 u - 4 u = 35 - 14
3 u = 21
1 u = 21 ÷ 3 = 7
Amount that the girls had in the end
= 4 u + 35 + 7 u + 9
= 4 u + 7 u + 35 + 9
= 11 u + 44
= 11 x 7 + 44
= $121
Answer(s): $121
