Please provide step by step instructions for how the problem was solved.
National Chemicals has an automatic chemical mixture that it has been using for the past 4 years. The mixer originally cost $18000. Today the mixer can be sold for $10000. The mixer can be used for 10 years more and will have a salvage value of $2500 at that time. The annual operating and maintenance costs for the mixer equal $6000/year. Because of an increase in business, a new mixer must be purchased. If an older mixer is retained, a new mixer will be purchased at a cost of $25000 and have a $4000 salvage value in 10 years. This new mixer will have an annual operating and maintenance costs equal to $5000/year. The old mixer can be sold and a mixer of larger capacity can be purchased for $32000. This mixer will have a $6000 salvage value in 10 years and will have annual operating and maintenance costs equal to $8000/year.
