E) isabel’s competition, who sells books and no other products, charges a shipping fee of $1.99 per book plus a fixed fee of $3 for each order. let x be the number of books purchased and f(x) be the price of shipping one order of books. write a function that expresses f(x) and explain the value of f(x) for x =

For this case we have the following data:

A shipping fee of $ 1.99 is charged for each book sold.

There is a fixed fee of 3 dollars per order.

We must express the total cost by a function of the form .

If x represents the number of books sold, we have an expression of the form:

That is, according to the number of books sold, represented by x, a different value will be obtained for the total cost given by f (x). For example:

If 3 books are sold, we have:

Thus, the total cost of 3 books is 8.97 dollars.
