Question 1 The Southeastern Division of LaPlace Power and Light Company is responsible for providing dependable electric service to customers in and around the areas of Metairie, Kenner, Destreban, LaPlace, Lutcher, Hammond, Pontchatoula, Amite, and Bogalusa, Louisiana. One material used extensively to provide this service is the 1/0 AWG aluminum triplex cable, which delivers the electricity from the distribution pole to the meter loop on the house. The Southeastern Division storeroom purchases the cable that this division will use. For the coming year, this division will need 499,500 feet of this service cable.

If Southeastern Division using the current policy, what is the new ROP? f) What is the annual inventory cost if the division purchased using the current policy?
