25 as much money as Usha. Cathy received another $32 from her uncle and Usha received $4 from her father. In the end, Cathy had $4 more than Usha. How much did the girls have altogether in the end?

+ 32 |
+ 4 |
| After |
2 u + 32 |
5 u + 4 |
If Usha received another $4 in the end, she would have the same amount of money as Cathy.
5 u + 4 + 4 = 2 u + 32
5 u + 8 = 2 u + 32
5 u - 2 u = 32 - 8
3 u = 24
1 u = 24 ÷ 3 = 8
Amount that the girls had in the end
= 2 u + 32 + 5 u + 4
= 2 u + 5 u + 32 + 4
= 7 u + 36
= 7 x 8 + 36
= $92
Answer(s): $92
