HopHeart Brewery is considering 3 different bottling machines. It is expected that each machine will be replaceable at the same cost when their useful life ends. The details of the machines are as follows:

Machine X has a useful life of 6 years. It costs $10,000 to purchase and $2,000 per year to maintain.

Machine Y has a useful life of 12 years. It costs $15,000 to purchase, and $1,000 per year to maintain.

Machine Z has a useful life of 8 years. It costs $20,000 to purchase, and $200 per year to maintain.

The appropriate planning horizon for analyzing these choices is 24 years
