A pizza taken out of the oven is 400 degrees fahrenheit, and is then placed in a 75 degree fahrenheit room. After 5 minutes the pizza is 150 degrees fahrenheit.
400 - 150 = 250 pizza's change in temp.
250 / 5 =50 degrees per minute - the drop in pizza's temperature.
400*75-1502=7500
7500/75=100
400-100*4=0=tasty
