Calculation of first year amortization using straight line method is given below:Amortization = (Cost of asset - Residual value) / Useful life of assetFirstly, we need to find the useful life of the asset using miles. We have,Total miles the jet will remain useful = 6,250,000Total miles the jet will fly in first year = 725,000Therefore, useful life of jet in years= Total miles the jet will remain useful / Total miles the jet will fly in first year= 6,250,000 / 725,000= 8.62 yearsNow, we can calculate the first year amortization using straight line method:Amortization = (Cost of asset - Residual value) / Useful life of assetAmortization = ($40,000,000 - $5,500,000) / 8.62 yearsAmortization = $3,604,182.51The first-year amortization on the jet using the straight-line method is $3,604,183.The book value of the asset at the end of the first year using the straight-line method will be:Book value of asset = Cost of asset - Accumulated amortizationBook value of asset at the end of the first year = Cost of asset - First year amortizationBook value of asset at the end of the first year = $40,000,000 - $3,604,183Book value of asset at the end of the first year = $36,395,817. Answer: $3,604,183 and $36,395,817
