Answer 1

oof. i am not good at these.

Answer 2

$23.52

Explanation:

So first you would have to find how much each one would be if you were buying one individual book. For that you would do 31.36/4 to get $7.84. Then since you found that for only 1 book, you would need to multiply that by 3 to get $23.52
