Question 11

The local convenience store makes personal sized pizzas. Currently, its process makes complete pizzas, fully cooked, for the customer. This process has a fixed cost of $18,000, and a variable cost of $1.85 per pizza. The owner is considering a different process that can make pizzas in two ways: completely cooked (as before), or partially cooked and then flash frozen for the customer to finish heating at home. This alternate process has a fixed cost of $24,000, but a lower variable cost (because much less energy is used in baking) of $1.05 per pizza.
