Vasquez Development Partners purchased new construction equipment for $430,000 at the beginning of the year. In addition, the company paid $32,000 for delivery charges. Management estimated that the equipment has an 8 year useful life, with a salvage value of $24,000. What is the yearly depreciation expense under the straight-line method? What is the net book value after year 4? Please help me with how you calculated the answer. Thank you!
