7 u |
|
Change |
+ $38 |
- $10 |
|
After |
1 u + $38 |
7 u - $10 |
8 u + $28 |
Amount of money Jen and Fiona has is the same in the end.
7 u - 10 = 1 u + 38
7 u - 1 u = 38 + 10
6 u = 48
1 u = 48 ÷ 6 = 8
Amount the girls have in the end
= 1 u + 38 + 7 u - 10
= 8 u + 28
= 8 x 8 + 28
= 64 + 28
= $92
Answer(s): $92
