Answer 2

Answer:

$19.50 is the difference between the books.

Step-by-step explanation:

What you do is you take 12.50 and times it by 15 to get $187.50.

You will then take the 6% and times it to 187.50 to get 11.25. You will then add it together to get $198.75 as your total for Barnes and Noble.

For Amazon, what you do is multiply 13.75 and 15 to get $206.25.

Then you will take the .80 and multiply it by 15 because it is per book is $12. You will then add it to 206.25 to get $218.25.

You will then minus the Barnes and Noble from the Amazon to get $19.50 as the answer.
