For accounting purposes, the value of assets (land, buildings, equipment) in a business are depreciated at a set rate per year. the value, v(t) of $393,000 worth of assets after t years, that depreciate at 15% per year, is given by the formula v(t) = vo(b)t. what is the value of vo and b, and when rounded to the nearest cent, what are the assets valued at after 7 years?

vo = $393,000, b = 0.15, and the value after 7 years is $0.67
vo = $393,000, b = 1.15, and the value after 7 years is $108,543.57
vo = $393,000, b = 0.85, and the value after 7 years is $47,721.43
vo = $393,000, b = 0.85, and the value after 7 years is $125,986.80
