. Kosar Manufacturing has collected the following information on one of its major products.

Most efficient production rate = 2,200 + X units per period

Production change costs = $30 per unit of change (from the most efficient production rate = 2,100 + X units/period)

Inventory costs = $7 per unit per period (on closing inventory balance)

Backorder costs = $15 per unit to carry demand into next period

Beginning inventory = "X*20" units
