Answer:

The equation is  5x + 2y = 20

Step-by-step explanation:

Total money Derek has = $20

Cost of hardcover books = $5

Cost of paperbacks = $2

We need to find equation in standard form that 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 $20

So we have

5x + 2y = 20

The equation is  5x + 2y = 20
