You have created a pizza company that focuses on very fast pizza availability for customers. You have made this happen by only providing 5 "flavors" of pizza.
An inexpensive pizza oven (container) can only cook 8 pizzas at one time every 17.0 minutes. You assume 5% inefficiency.
If you plan for selling 143 pizzas each 2 hour lunch time, how many ovens should your kitchen have?
