A cardboard box manufacturer invested $30,000 for equipment, utility, power station, and rent of manufacturing buildings. The cost for ship, labor and materials for each box are $2, $2, and $4, respectively. The unit price for each box is $12. The average thickness of the cardboard is 1.0 in. (i.e., mean value), and the manufactured pipes are in a range of (0.95 in, 1.05 in). The standard deviation is 0.025 in. If a client needs 10,000 boxes, what will be the break-even point? (Consider 100 boxes in storage and use the new unit cost considering rejection for the boxes in storage)
