Answer:

Step-by-step explanation:

Number of excellent condition paperbacks = x

Number of fair-condition paperbacks = f

To find total cost we multiply unit rate 2.50 by x and unit rate 0.50 by f and then add

Hence total cost for buying x excellent-condition paperbacks and f fair-condition paperbacks

[tex]=2.50x + 0.50f[/tex]
