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
