Answer: $7,875 per year for each of the first two years.
Explanation: The method to calculate the amount of depreciation using the straight line method is to subtract the salvage price from the purchase price and then divide it by the numbers of years in its useful life.
($35,400 - 3,900)/4 = $31.500 / 4 = $7,875 per year
$7,875 is the amount of depreciation for each year of the four years of the truck’s useful life.
