Maintaining Optimum Inventory Problem

Question

Powered by Koffe (PBK) is a new campus coffee store. PBK uses 50 bags of whole bean coffee every month, and you may assume that the demand is perfectly steady throughout the year. PBK has signed a year-long contract to purchase its coffee from a local wholesaler, Phish Roasters, for a price of $25 per bag and an $85 fixed cost of placing an order which is independent of the size of the order. The holding cost due to storage etc. is $1.50 per bag per month.

b. Given your answer in (a), how many times does PBK order in a year?

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
