X Company is trying to decide whether to continue using old equipment to make Product A or replace it with new equipment that will have lower operating costs. The following information is available:

• The new equipment will cost $45,000. Disposal value at the end of its 6-year useful life will be $5,000.
• The old equipment was purchased 3 years ago for $20,000. It can be sold immediately for $5,000 but will have zero disposal value in 6 years.
• Maintenance work, costing $3,500, will be necessary on the old equipment in Year 3.
• The new equipment will result in $10,000 of operating cost savings each year.

Assuming a discount rate of 6%, what is the net present value of replacing the old equipment with the new equipment?
