For this case we have:


2b: Variable that represents the amount of books Tim had.

k: Variable that represents the price of each book

y: Variable that represents the quantity of books not sold.

Then we have, according to the statement that, the quantity of books sold is given by:


2b-y

Thus, the total dollar amount received for the books sold are:


k (2b-y)
