Marley company sells drip coffee makers used in business offices. Its beginning inventory of coffee makers was 400 units at $50 each. During the year, Marley made two purchaases of coffee makers. The first purchase was 500 units at $70 per unit; the second was a 600-unit-purchase at $75 per unit. During the period Marley sold 1300 coffee makers at a price of $100. Due to the introduction of K cups in the last part of the year, the sales price of the drip coffee makers dropped to $75 and the replacement cost of drip coffee makers that Marley would buy in the future to $68.
