We have been given that Mary had 199 dollars to spend on 8 books. After buying them she had 15 dollars. We are asked to find the cost of each book.

First of all, we will subtract 15 from 199 to find amount spent on 8 books.

$\text{Money spent on 8 books}=\$199-\$15$

$\text{Money spent on 8 books}=\$184$

Now we will divide amount spent on 8 books by 8 to find cost of each book.

$\text{Cost of each book}=\frac{\text{Cost of 8 books}}{8}$

$\text{Cost of each book}=(\$184)/(8)$

$\text{Cost of each book}=\$23$

Therefore, the cost of each book is $23.
