Emery Pharmaceutical uses an unstable chemical compound that must be kept in an environment where both temperature and humidity can be controlled. Emery uses 800 pounds per month of the chemical, estimates the holding cost to be 50%
of the purchase price (because of spoilage), and estimates order costs to be $50 per order. The cost schedules of two suppliers are as follows:
VENDOR 1 VENDOR 2 QUANTITY PRICE/LB QUANTITY PRICE/LB 1–499 $17.00 1–399 $17.10 500–999 16.75 400–799 16.85 1,0001 16.50 800–1,199 16.60 1,2001 16.25
