Answer:
Using the straight-line depreciation method, the annual depreciation amount is $595, and after three years, the total depreciation would be $1,785 (595 x 3).
To find the book value at the end of the third year, we subtract the total depreciation from the original cost of the computer system:
$3,500 - $1,785 = $1,715
Therefore, the correct answer is (B) $1,715.
