John had a stock of 1200 books in his bookshop. He sold 75 on Monday, 50 on Tuesday, 64 on Wednesday, 78 on Thursday and 135 on Friday. What percentages of the books were not sold?

Respuesta :

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%
