Question

Colleen plans to start a small business by making and selling skirts. A sewing machine costs $250, and she estimates that she will spend $15 on materials for each skirt. Which expression represents Colleen’s total costs, in dollars, for making x skirts?

Answer 1

Let C(x) be the function which calculates the total cost of making x skirts.

There is going to be a fixed constant, 250, to which we will add 15$ per x skirts.


So C(x)=250+15x

Answer: 250+15x

Answer 2

Answer:

$C(x) = 15x + 250$

Step-by-step explanation:

Given : Colleen plans to start a small business .

               A sewing machine costs $250,

               She will spend $15 on materials for each skirt

To Find :  

Expression that represents Colleen’s total costs, in dollars, for                     making x skirts C(x)

Solution :

Let x denotes the no. of skirts and Sewing machine cost will remain constant

Cost she will spend on each skirt is $15.

⇒$C(x) = 15x + 250$

Thus , Expression that represents Colleen’s total costs, in dollars, for                     making x skirts C(x) is   $C(x) = 15x + 250$
