Frank’s Fight Milk Factory has a filling machine that initially cost $40, 000. Frank estimates that the useful life of the machine will be 12 years, at which time its salvage (scrap) value will be $4, 000. Assume that the price depreciates linearly. a. What is the rate of depreciation of the filling machine per year ? b. Write a linear function that gives the value of this machine in terms of the years t after its initial purchase (0 ≤ t ≤ 12). c. What will be the value of the machine in 6 years ?
