Answer: f(x)= 1.99x +3

f(0) =3

For F(0) there is a order of 0 books.

Explanation:

Hi, to answer this question we have to write an equation with the information given:

The price of the shipping ( f(x)) is equal to the cost of the fixed fee per order (3) plus the product of the number of books ordered (x) and the cost of the fee per book (1.99).

f(x)= 1.99x +3

for f(0) = 1.99(0)+3

f(0) =3

For F(0) there is a order of 0 books. The price is only for the shippping.
