You noticed that MusicChange Us Incorporaton makes musical instruments and most of them are guitars. However, one of their very popular products is an acoustic guitar that has an annual demand of 4,000 units. The setup cost for each production batch is $1,500. In addition to that, it costs MusicChange Us $12 to carry a guitar in finished goods inventory for the whole year. Required: 1.
