Question

a printing service charges a set - up fee of $13.00 for each order and 7 cents more for each copy. the total cost, c (in dollars), for an order of x copies is given by the following function.
c(x)=13.00 + 0.07x
what is the total cost for an order of 20 copies?
dollars

Explanation:

Step1: Identify the value of x

We need to find the total cost for 20 copies, so \( x = 20 \).

Step2: Substitute x into the cost function

The cost function is \( C(x)=13.00 + 0.07x \). Substitute \( x = 20 \) into the function:
\( C(20)=13.00+0.07\times20 \)

Step3: Calculate the multiplication part

First, calculate \( 0.07\times20 = 1.4 \)

Step4: Calculate the total cost

Then, add 13.00 and 1.4: \( 13.00 + 1.4=14.4 \)

Answer:

14.4
