The linear depreciation method assumes that an item depreciates the same amount each year. Suppose a new piece of machinery costs $46,000 and it depreciates $1,050 each year for t years. Set up a linear function that yields the value of the machinery after t years.
A. f ( t ) = 1,050t - 46,000 B. f ( t ) = 1,050t + 46,000 C. f ( t ) = 46,000 - 1,050t D. f ( t ) = 46,000t + 1,050 E. f ( t ) = 46,000t - 1,050
