Yen had
37 as much money as Abi. Yen received another $48 from her aunt and Abi spent $8 on some staplers. In the end, Yen and Abi had an equal amount of money. How much money did the girls have altogether in the end?

Total |
Before |
3 u |
7 u |
|
Change |
+ $48 |
- $8 |
|
After |
3 u + $48 |
7 u - $8 |
10 u + $40 |
Amount of money Yen and Abi has is the same in the end.
7 u - 8 = 3 u + 48
7 u - 3 u = 48 + 8
4 u = 56
1 u = 56 ÷ 4 = 14
Amount the girls have in the end
= 3 u + 48 + 7 u - 8
= 10 u + 40
= 10 x 14 + 40
= 140 + 40
= $180
Answer(s): $180
