James buys a jar of hot sauce.   Each serving is .5 ounces.  He uses 3 servings every day.  if the container is 2 ounces less than 1 quart how many days will it last?
A quart is 32 ounces so this jar is 32-2=<T>subtract(32, 2)=30 ounces
James uses 3*.5=<T>multiply(3, 0.5)=1.5 ounces a day
So it last 30/1.5=<T>divide(30, 1.5)=20.0 day
