Question

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=0

Graph the function

Answer 1

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.

Answer 2

i think it could be xf(0) or x 1.99(0)
