Answer:

The equation is 5x + 2y = 20

Step-by-step explanation:

Derek's money in total = $20

Cost of hardcover books = $5

Cost of paperback books = $2

We have to discover the equation in standard structure decides the number x of hardcover books and the number y of paperback books he can purchase.

So in total hardcover = 5x and paperback = 2y

Therefore the equation is 5x + 2y = 20
