The linear depreciation method assumes that an item depreciates the same amount each year. Suppose a new piece of machinery costs $33,000 and it depreciates $850 each year for t years. Set up a linear function that yields the value of the machinery after t years.
A. f ( t ) = 850t - 33,000 B. f ( t ) = 850t + 33,000 C. f ( t ) = 33,000 - 850t D. f ( t ) = 33,000t + 850 E. f ( t ) = 33,000t - 850
