There are several mutually exclusive ways Grazemont Dairy can meet a requirement for a filling machine for its creamer line. One choice is to buy a machine. This would cost $65,000 and last for six years with a salvage value of $10,000. Alternatively, it could contract with a packaging supplier to get a free machine. In this case, the extra costs for packaging supplies would amount to $15,250 per year over the six-year life (after which the supplier gets the machine back with no salvage value for Grazemont). The third alternative is to buy a used machine for $30,000 with zero salvage value after six years. The used machine has extra maintenance costs of $3000 in the first year, increasing by $2500 per year. In all cases, there are installation costs of $6000 and revenues of $18,000 per year.
