4.5 The price of a factory machine is R900000 but depreciates at 5% per annum. Calculate the depreciated value of the machine after 6 years if: 4.5.1 the depreciation is at simple interest rate. (3) 4.5.2 the depreciation is at compound interest rate. (3) 4.6 The rate of inflation is at 6% per annum compounded annually. Determine the price of the new machine in 4.5 after 6 years.
