An office machine is purchased for 58400. Assume that its salvage value, V, in dollars, depreciates, according to a method called double declining balance, by 205% each year and is given by V() = 8400(0.80), where t is the time, in years, after purchase. a) Find V(9). and explain its meaning b) Find V'(9), and explain its meaning. c) When will the salvage value of the office machina be half of the purchase price? a) V(9) = (Round to the nearest cent as needed.) The expression V(9) means that after year(s). the salvage value b) V'(9)= s 4 (Round to the nearest cent as needed.) The expression V'(9) means that after year(s), the salvage value c) The salvage value of the office machine will be half of the purchase price after years. (Round to two decimal places as needed )
