Given that,
Value of a computer= $6500
Depreciation rate= 14.3%
Now, depreciation after 1st year= 6500 x 14.3%
Depreciation after 1st year= 929.5
Value of a computer after 1 year = 6500 – 929.5= 5570.5
Depreciation after 2nd year= 5570.5 x 14.3%
Depreciation after 2nd year= 796.58
Value of the computer after 2 year=5570.5-796.58=4773.92
Depreciation after 3rd year= 4773.92 x 14.3%
Depreciation after 3rd year= 682.67
Value of the computer after 3 year= 4773.92-682.67= 4091.25
Therefore, the value of the computer after 3 year is $4091 approximately.
