Mike’s mother wants new winter tires installed on her vehicle. She has asked Mike to check out prices. Mike has just stopped by the shop where his friend Carmen works. Carmen says they have a mid-season special right now. Snow tires the size Mike’s mother needs are regularly $199.00 each; but, if she purchases the tires this week, she will get all four tires for the price of three. Mike knows that, at the local building centre, the same tires are regularly $209.00 apiece, but they are on sale right now for 30% off.

 

Which is the better buy?

 

Mike likes the idea of working at a shop like Carmen’s. He wonders how much Carmen earns and how the shop sets its tire prices.
