Question

Kerry bought 3 books that were all the same price he paid a total of $40.20 what is the cost of one book

Answer 1

Well if there were three books that were all the same price and the sum was $40.20, you would simply divide the sum by three (amount of books). This is how the equation would look:

40.20/3= 13.40

Therefore, the price of one of the books is $13.40

Answer 2

To find the cost of one book you need to divide 40.20 by 3.
40.20/3= 13.4
Dont forget the dollar sign - $13.4
Cost of one book is $13.4
