2 Inventory Cost Model Problem 4. Suppose a company needs 1,000 booklets printed per year. The cost to prepare and run the printers is $600. It costs $2 to print a booklet and $1 to store it for a year. Use the inventory cost model to find the number of booklets that should be printed per ring to minimize production and storage costs. Inventory Cost Model: total production cost = (number of runs)(cost per run) + (total number of items produced)(cost per item) total storage cost = (average number stored)(storage cost per item) Set $x$ to be the number of items in a production run. 1. In terms of $x$ how many runs are needed per year? 2. We assume that inventory is depleted at a constant rate and completely depleted between production runs. Thus the average number of items stored is $\frac{x}{2}$. Using this, write a function $C(x)$ for the total production and storage costs. 3. Find the value of $x$ which will minimize $C(x)$.
