Storing one frozen pie for a year costs $1.25. When the grocery store reorders pies, there is a fixed cost of $4.25 per order as well as $0.85 per ple. Each year, they sell 1750 frozen pies. What is the optimal number of pies to order in each order to minimize their total inventory costs Get help: Written Example Points possible: 10 This is eitempa 1 of 5 Submit SAMSUNG

Explanation / Answer

Let

x = number of items per order.

Yearly cost = 1.25*(x/2) =0.625x

Yearly reorder cost = (4.25+0.85x) *1750/x

Total cost C(x)=0.625x +(4.25+0.85x) *1750/x

Find derivative

C'(x) =0.625 - 7437.5/x^2

Set to 0 as

x² =7437.5/0.625

x² =11900

x is about 109

Hence optimum number of pie per order is 109.
