Answer:
$11
Step-by-step explanation:
To solve this you'd subtract 16 from the total amount of money she had and divide by the 9 books. Then you get 11.
Cost of each book is equals to $11.
" Cost is defined as the amount of money paid to purchase anything."
According to the question,
Total money with Jessica = $115
Number of books = 9
Amount left with Jessica after buying 9 books = $16
Total money spend on 9 books = $ (115- 16)
= $ 99
Cost of 9 books = $99
Cost of each book = [tex]\frac{99}{9}[/tex]
= $11.
Hence, cost of each book is equals to $11.
