Final answer:
To calculate the depreciation each year, the straight-line method is used to divide the difference between the purchase price and residual value by the useful life. The declining balance method uses the book value and a depreciation rate.
Step-by-step explanation:
To calculate the amount of depreciation to be charged each year using the straight-line method, subtract the residual value from the purchase price and divide by the useful life in years. In this case, the annual depreciation would be ($183,000 - $13,000) / 4 = $42,500.
To calculate the amount of depreciation to be charged each year using the declining balance method, multiply the book value at the beginning of each year by the depreciation rate. In this case, the annual depreciation rate would be 5% (0.05). The depreciation would be: Year 1: $183,000 * 0.05 = $9,150, Year 2: ($183,000 - $9,150) * 0.05 = $8,607.50, Year 3: ($183,000 - $9,150 - $8,607.50) * 0.05 = $8,177.88, Year 4: ($183,000 - $9,150 - $8,607.50 - $8,177.88) * 0.05 = $7,769.99.
