Solve the problem.A piece of equipment was purchased by a company for $10,000 and is assumed to have a salvage value of $3,000 in 10 years. If its value is depreciated linearly from $10,000 to $3,000, find a linear equation in the form V = mt + b, t time in years, that will give the salvage value at any time t, 
A. T = - 700V + 10,000 B. V = - 700t + 10,000 C. V = - 700t - 10,000 D. V = 700t + 10,000
