4) Answer the following: a) Tracy Company sells three different types of home heating stoves (gas, wood, and pellet). The cost and net realizable value of its inventory of stoves are as follows. Gas Cost(S) 84,000 250,000 112,000 Net Realizable Value (S) 79,000 280,000 101,000 Wood Pellet Determine the value of the company's inventory under the lower-of-cost-or-net realizable value approach. b) Calculate the depreciation using MACRS approach for an asset which costs $85,000 and is being depreciated using a 5-year normal recovery period (depreciation rate is as follows: 20%, 32%, 19%, 12%, 12% and 5%). Will the depreciation amount be difference in case of straight line method when the scrap value of the asset is $5,000
