Please help with the following problem regarding inventory management.
The Acme Grocery store started a Coupons Instantly program. It requires a debit card with a minimum of $300, so the customer can buy as many coupons as they want. As a promotional gimmick they are offering pens. The pens are given away to new coupon holders. The additional pens needed have become a problem for inventory. The manager estimates:
D = 700 pens per year
HC = $4 per pen per year
OC = $30 per order
a. How many pens should the manager order at one time?
b. For the optimal order quantity, figure out the total inventory cost for the year.
