1. Shirley is studying depreciation in her engineering management course. The instructor asked her to graphically compare the total percent of first cost depreciated for an asset costing B dollars over a life of n = 5 years for DDB and 125% DB depre- ciation. Help her by developing the plots of percent of B depreciated versus years. Use a spread- sheet unless instructed otherwise.
2. Develop the depreciation and book value schedules using the GDS MACRS method for oil and gas drilling equipment that cost $1.2 million. A salvage value of $300,000 is estimated.
