79 as much money as Yen. Victoria received another $42 from her aunt and Yen received $4 from her mother. In the end, Victoria had $2 more than Yen. How much did the girls have altogether in the end?

+ 42 |
+ 4 |
| After |
7 u + 42 |
9 u + 4 |
If Yen received another $2 in the end, she would have the same amount of money as Victoria.
9 u + 4 + 2 = 7 u + 42
9 u + 6 = 7 u + 42
9 u - 7 u = 42 - 6
2 u = 36
1 u = 36 ÷ 2 = 18
Amount that the girls had in the end
= 7 u + 42 + 9 u + 4
= 7 u + 9 u + 42 + 4
= 16 u + 46
= 16 x 18 + 46
= $334
Answer(s): $334
