Rates and Equations in Pie Baking

The video tutorial compares the pie production rates of two bakeries, Zombie Pies and Vampire Pies, using proportional relationships and direct variation. It explains how to write equations representing these relationships, focusing on the coefficient as the rate. The tutorial calculates the rates for both bakeries, finding Zombie Pies at 40.5 pies per hour and Vampire Pies at 40 pies per hour. It concludes by comparing these rates to determine which bakery has a larger rate of change.
