Material A does not have a resale value outside of the company, as it is not used commonly in the engineering industry. It could be used as a substitute for another material which currently costs 10% less than the original cost of material A. 2. The price for material B has increased to twice the amount at which it was first purchased. Material B can be resold at its current market price, in which case the costs of disposal are 12% of the selling price. If not sold, any material B could be used on any future contracts as it does not deteriorate. 3. The plant that would be required is common to both contracts. If it were used on the Bela Bela contract, all of the plant would be required due to the nature of the work to be undertaken. However, if the Makhado contract goes ahead, less plant will be required.
