$5 each and paperbacks cost $2
each. what equation in standard
form determines the number x ot
hardcover books and the number y
of paperback books he can buy?

The equation is  5x + 2y = 20

Step-by-step explanation:

Total money Derek having = 20 $

Cost of hardcover book = 5 $

Cost of paperbacks = 2 $

We need to find equation in standard  form determines the number x of hardcover books and the number y  of paperback books he can buy.

Total cost of x hard cover books = 5x

Total cost of y paperback books = 2y

He has only 20 $

So we have

                  5x + 2y = 20

The equation is  5x + 2y = 20
