Answer:_______________ |
1) The value of a machine depreciates by 5% each year. A man pays Answer: 2.84 SOLUTION 1 : Given : Present value of the machine P = Rate of depreciation r = 5% Number of years n = 3 The value of the machine after n years = P[1-(r÷100)]n = 19817[1-(5÷100)]3 = 19817[1-0.05]3 = 19817[0.95]3 = 2.83965246792 =

2) The value of a machine depreciates by 4% each year. A man pays Answer: 4.69 SOLUTION 1 : Given : Present value of the machine P = Rate of depreciation r = 4% Number of years n = 5 The value of the machine after n years = P[1-(r÷100)]n = 16668[1-(4÷100)]5 = 16668[1-0.04]5 = 16668[0.96]5 = 4.68825477001 =
|
3) The value of a machine depreciates by 7% each year. A man pays Answer: 1.91 SOLUTION 1 : Given : Present value of the machine P = Rate of depreciation r = 7% Number of years n = 2 The value of the machine after n years = P[1-(r÷100)]n = 15315[1-(7÷100)]2 = 15315[1-0.07]2 = 15315[0.93]2 = 1.90527599609 =
|
4) The value of a machine depreciates by 8% each year. A man pays Answer: 1.89 SOLUTION 1 : Given : Present value of the machine P = Rate of depreciation r = 8% Number of years n = 2 The value of the machine after n years = P[1-(r÷100)]n = 17279[1-(8÷100)]2 = 17279[1-0.08]2 = 17279[0.92]2 = 1.89211529345 =
|
5) The value of a machine depreciates by 6% each year. A man pays Answer: 2.81 SOLUTION 1 : Given : Present value of the machine P = Rate of depreciation r = 6% Number of years n = 3 The value of the machine after n years = P[1-(r÷100)]n = 18586[1-(6÷100)]3 = 18586[1-0.06]3 = 18586[0.94]3 = 2.8086264369 =
|
6) The value of a machine depreciates by 3% each year. A man pays Answer: 1.96 SOLUTION 1 : Given : Present value of the machine P = Rate of depreciation r = 3% Number of years n = 2 The value of the machine after n years = P[1-(r÷100)]n = 18358[1-(3÷100)]2 = 18358[1-0.03]2 = 18358[0.97]2 = 1.95884059517 =
|
7) The value of a machine depreciates by 5% each year. A man pays Answer: 1.93 SOLUTION 1 : Given : Present value of the machine P = Rate of depreciation r = 5% Number of years n = 2 The value of the machine after n years = P[1-(r÷100)]n = 19280[1-(5÷100)]2 = 19280[1-0.05]2 = 19280[0.95]2 = 1.93187265785 =

8) The value of a machine depreciates by 3% each year. A man pays Answer: 2.90 SOLUTION 1 : Given : Present value of the machine P = Rate of depreciation r = 3% Number of years n = 3 The value of the machine after n years = P[1-(r÷100)]n = 12026[1-(3÷100)]3 = 12026[1-0.03]3 = 12026[0.97]3 = 2.90273652106 =
|
9) The value of a machine depreciates by 3% each year. A man pays Answer: 3.84 SOLUTION 1 : Given : Present value of the machine P = Rate of depreciation r = 3% Number of years n = 4 The value of the machine after n years = P[1-(r÷100)]n = 17085[1-(3÷100)]4 = 17085[1-0.03]4 = 17085[0.97]4 = 3.8370564773 =
