Kindly show solution. Thanks!

1. A five-year-old machine, Machine X, purchased for $100000 is not able to meet today's market demands. Its operating cost is higher than expected, so it will be used for only 4 more years. Its operating cost this year will be $40,000, increasing by $2000 per year through the end of its useful life. The challenger, Machine Y will cost $140,000 with a $60,000 salvage value after its 10 -year ESL. Its operating cost is expected to be $10,000 for year 1 , increasing by $500 per year thereafter. What is the market value for machine X that would make the two machines equally attractive at an interest rate of 12% per year
