. Do each of the following:

a) Calculate the straight-line and sum-of-years-digits depreciation schedules for $450,000 worth of exercise equipment purchased for college athletes to use in their workouts. It is projected that the equipment will last five

years and have a salvage value of $50,000.

b) Suppose the USC football team purchases an $800,000 video recording system so the coaches can review games.

Calculate the double-declining balance depreciation schedule and determine the salvage value if the system is

expected to last four years.
