Answer:
The present worth of aircraft = $29137.82
Explanation:
Given the cost of money (r ) = 10%
The initial cost of small aircraft = $35000
Annual repair and maintenance costs (A) = $20000
Salvage valaue = $10000
Now calculate the present value of aircraft by adding the initial cost of annual maintenance and salvage value and subtracting the initial cost.
[tex]Present worth = initial cost + \frac{A[1-(1+r)^{-n}]}{r} - \frac{Salvage \ value}{(1 + r)^{n}} \\= 35000 + \frac{20000 [1 – (1+ 0.01)^{-2}]}{0.01} - \frac{10000}{(1 + 0.01)^{2}} \\= $29137.82[/tex]
