Capital Budgeting Maintenance Costs

"Beryl's Iced Tea currently rents a bottling machine for $50,000 per year, including all maintenance expenses. It is considering purchasing a machine instead, and is comparing two options:
a)   Purchase the machine it is currently renting for $150,000. This machine will require $20,000 per year in ongoing maintenance expenses.
b)   Purchase a new, more advanced machine for $250,000. This machine will require $15,000 per year in ongoing maintenance expenses and will lower bottling costs by $10,000 per year. Also, $35,000 will be spent up front in training the new operators of the machine.
