2. Students will be asked work out the best buy in the following problem

6 pairs of socks for $429 or 4 pairs of socks for $284
Unit Price = $429/6                                                                                           Unit Price =$284/4
=$71.50                                                                                                                                 =$71.00

-Calculate the unit cost
-Unit cost/price =(Total cost )/(Number of goods /services)
