Answer:
The present worth of aircraft = $29137.82
Step-by-step 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.
![Present worth = initial cost + (A[1-(1+r)^(-n)])/(r) - (Salvage \ value)/((1 + r)^(n)) \\= 35000 + (20000 [1 – (1+ 0.01)^(-2)])/(0.01) - (10000)/((1 + 0.01)^(2)) \\= $29137.82](https://img.qammunity.org/2021/formulas/business/college/4iktoewrx0l2fmmama74tz7rug5zzm1ax0.png)
