Answer:
depreciation expense 140,000 dollars
Step-by-step explanation:
Units of production will divide the cost of the jet over the total expected miles of the plain over his useful life:

$ 28,000,000 / 200,000,000 miles = 0.14 dollars per mile
We are going to multiply this rate over the miles flight this year.
$ 0.14 per mile x 1,000,000 miles= 140,000 dollars of depreciation
