Ann Chovies, owner of the Perfect Pasta Pizza Parlour, uses 20 pounds of pepperoni each day in preparing pizzas. Order costs for pepperoni are $10.00 per order, and holding costs are 4 cents per pound per day. Lead time for each order is 3 days, and the pepperoni itself costs $3.00 per pound. If she were to order 80 pounds of pepperoni at a time, what would be the length of an order cycle?
