Coffee Culture Companys managers must decide which of two coffee grinders Y or Z to buy. The grinders have the same purchase price but different revenue and cost characteristics. The company currently owns Grinder X, which it bought three years ago for $10,000 and which has accumulated depreciation of $9,000 and a book value of $1,000. Grinder X is now obsolete as a result of advances in technology and cannot be sold or traded in.
