In order to vitrify a formulated ceramic tile, it is subjected to high temperature through a kiln at 1100. A certain start-up bought a new kiln for their ceramic tile product at 300,000.00 and has a salvage value of 20,000.00 at the end of 6 years. It is expected that their product will earn 175,000.00 per year. However, the annual maintenance cost of the kiln is projected to be at 100,000.00 at the end of year one and will increase by 5,000.00 per year. If the MARR is 10%:
