The straight-line method of depreciation is calculated by subtracting the salvage value of an asset from its cost and dividing the result by the useful life of the asset. In this case, the machine cost is N12,000, and it has a useful life of 4 years with an expected disposal value of N400. To calculate the annual depreciation expense, we subtract the salvage value from the cost and divide by the useful life: (N12,000 - N400) / 4 = N2,900 So, the annual depreciation expense is N2,900. To find the accumulated depreciation at the end of year 3, we need to multiply the annual depreciation expense by the number of years that have passed. Therefore, the accumulated depreciation at the end of year 3 would be: N2,900 x 3 = N8,700 Therefore, the accumulated depreciation at the end of year 3 using the straight-line method is N8,700. Therefore, option (C) is the correct answer.
