Lori owns a truck with a book value of $20,000 (as of two weeks ago). Last week, she paid insurance on the truck ($2,200 for the year). She also got an annual check-up and oil change ($100 cost). Finally, she got a cover installed on the rear bed ($4,000 cost), which will allow her to transport expensive furniture. The cover is expected to last ten years. The truck's book value is now: $26300 $24000 $20000 $24100
