Determine the linear equation for each club.

Question

You are planning to purchase CDs from a music club. The following information is given:

 

Club A:    Cost of each CD: $15.95

                 No membership fee

 

Club B:    Cost of each CD: $13.95

                 Membership Fee: $22 per                        year

Answer 1

The cost depends on the number of CDs.

 

Let x = the number of CDs

Let y = total cost of CDs

 

 

Club A:  You only pay each time you buy a CD.

 

y = 15.95x

 

 

Club B:  Before you buy the CDs, you start paying for the membership.  If the membership is yearly, then

 

y = 13.95x + 22
