The first step is to find the unit price of each seller. We were told that Staples sells folders in packs of 12 for 4.80. It means that the price per folder is
4.80/12 = 0.4 per folder
Also, Office max sells folders in packs of 17 for 7.50. It means that the price per pack is
7.50/17 = 0.44
Since the unit rate of Staples is low, then Staples has the better deal
