Basic Economic Order Quantity (EOQ) Model, economics homework help

The owner of a diner has summarized the price lists from four potential vendors (see the following table) who want to supply her with cooking oil. Monthly usage is 300 gallons, ordering cost is $10 per order, and the monthly carrying cost is $ .50 a gallon.

Which vendor should she use, and what order quantity is best if she wants to minimize total annual costs (TMC).

VENDOR W VENDOR X VENDOR Y VENDOR Z

Quantity Price Quantity Price Quantity Price Quantity Price

1-99 $25 1-79 $25 1-25 $27 1-59 $26

100-399 24 80-139 24 26-89 25 60-139 25

400+ 22 140-299 23 90-199 24 140-249 24

300+ 22 200+ 23 250+ 23

Since demand and carrying costs are both expressed on a monthly basis, you will need to multiply these values by 12 to put into annual terms.
