Question

a printing service charges a set - up fee of $10.25 for each order and 15 cents more for each copy. the total cost, c (in dollars), for an order of x copies is given by the following. c = 0.15x + 10.25. what is the total cost for an order of 30 copies? dollars

Explanation:

Step1: Identify the value of x

Given the number of copies $x = 30$.

Step2: Substitute x into the cost - formula

Substitute $x = 30$ into the formula $C=0.15x + 10.25$. So $C=0.15\times30+10.25$.

Step3: Calculate the first term

$0.15\times30 = 4.5$.

Step4: Calculate the total cost

$C=4.5 + 10.25=14.75$.

Answer:

$14.75$
