A printing service charges a set-up fee of $11.00 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)=11.00+0.07x
What is the total cost for an order of 30 copies?
To find the total cost for an order of 30 copies, we can plug in x=30 into the function C(x)=11.00+0.07x:
C(30) = 11.00 + 0.07(30)
= 11.00 + 2.10
= $13.10
Therefore, the total cost for an order of 30 copies is $13.10.
To find the total cost for an order of 30 copies, we need to substitute the value of x (which is 30) into the function C(x) = 11.00 + 0.07x.
C(30) = 11.00 + 0.07(30)
= 11.00 + 2.10
= 13.10
Therefore, the total cost for an order of 30 copies is $13.10.
