• When the y-value increases, then the relationship is linear.

• When the y-value decreases, then the relationship is linear.

• When the slope or rate of change is the same at every point, then the relationship is linear.

• You cannot determine from the table if the relationship is linear.

Rachel is getting married, but she is on a budget. She is buying her invitations and has narrowed it down to two stores, Party Time and I Do Bridal. Party Time charges a $20 set up fee and then $1.50 per invitation. I Do Bridal charges a $40 set up fee and then $1.00 per invitation.

Create a mathematical model (equation) to represent the total cost if Rachel bought her invitations from Party Time. Let x represent the number of invitations.

Rachel is getting married, but she is on a budget. She is buying her invitations and has narrowed it down to two stores, Party Time and I Do Bridal. Party Time charges a $20 set up fee and then $1.50 per invitation. I Do Bridal charges a $40 set up fee and then $1.00 per invitation.

If Rachel had a small wedding and only needed 35 invitations, which store would you recommend to her and why?

• I Do Bridal because it is cheaper than Party Time if Rachel buys less than 40 invitations.

• I Do Bridal because it will always be cheaper than Party Time.

• Party Time because it is cheaper than I Do Bridal if Rachel buys less than 40 invitations.

• It does not matter because they would cost the same amount.
