1) The value of a machine depreciates by 8% each year. A man pays 17964 for the machine. Find its value after 4years. Answer: 3.58 SOLUTION 1 : Given : Present value of the machine P = 17964 Rate of depreciation r = 8% Number of years n = 4 The value of the machine after n years = P[1-(r÷100)]n = 17964[1-(8÷100)]4 = 17964[1-0.08]4 = 17964[0.92]4 = 3.58010028371 = 3.58

2) The value of a machine depreciates by 8% each year. A man pays 17000 for the machine. Find its value after 4years. Answer: 3.58 SOLUTION 1 : Given : Present value of the machine P = 17000 Rate of depreciation r = 8% Number of years n = 4 The value of the machine after n years = P[1-(r÷100)]n = 17000[1-(8÷100)]4 = 17000[1-0.08]4 = 17000[0.92]4 = 3.58010028371 = 3.58
