Answer:

Books in inventory= 66.5%

Step-by-step explanation:

First, we determine the number of books sold:

Books sold= 75 + 50 + 64 + 78 + 135= 402 books

Now, using the following formula, the percentage of books in inventory:

Books in inventory= [(books sold/total books) -1]*100

Books in inventory= [1 - (402/1,200)]*100

Books in inventory= 66.5%
