Problem
Flemming Accessories makes paper cutters that are used in offices and art stores. The mini-slicer has been one of their most popular items: annual demand is 6,750 units and is constant throughout the year. Kristen Flemming, the company's owner, makes the mini-batch cutters. On average, Kristen can make 125 per day. The demand for these cutters during the production process is 30 per day. The setup cost for the equipment needed to make mini-cutters is $150. Annual holding costs are $1 per mini-slicer. How many mini-slicers should Kristen produce in each batch?
