The first store charges $3 for 6 apples while the second store charges $4 for 10 apples. How many cents can you save on each apple from buying $4 for 10 apples than from $3 for 6 apples? Let's be accurate as possible.
User
In the first store, each apple costs $3 / 6 = $0.5. In the second store, each apple costs $4 / 10 = $0.4. So, you can save $0.5 - $0.4 = $0.1 on each apple from buying $4 for 10 apples than from $3 for 6 apples. In cents, this is equal to $0.1 x 100 = 10.
The answer: 10.
