6. 5.28 A major repair on the transmission of Judy’s 3-year old car cost her

$2000 because the warranty expired after 2 years of ownership. Based on this experience, she will plan on additional $2000 expenses every 3 years henceforth. Also, she spends $800 every 2 years for regular maintenance. This is in years 2, 4, 6, 8, and 10 when she plans to donate the car to charity. Use these costs to determine the equivalent annual amount for years 1 through infinity that Judy should put aside. Assume cars she owns in the future will have the same cost pattern and let i = 5% per year. Solve using

(a) tabulated factors, and

(b) a spreadsheet.
