A corporate executive jet with a seating capacity of 20 has the following cost factors:

Item Cost
Initial cost $12,000,000
Service life 15 years
Salvage value $2,000,000
Crew costs per year $225,000
Fuel cost per mile $1.10
Landing fee per landing $250
Maintenance costs per year $237,500
Insurance costs per year $166,000
Catering cost per passenger round trip $75

The company flies three round trips from Boston to London and back per week, a distance of 3,280 miles one way. How many passengers must be carried on an average round trip in order to justify the jet if alternative commercial airline first-class round trip fare is $ 3,400 per passenger? The firm’s MARR is 15%.

Consider the following six alternatives. They have 20-year useful lives and no salvage value. If the minimum attractive rate of return is 6%, which alternative should be selected?
A B C D E F
Cost $ 4,000 $ 2,000 $ 6,000 $ 1,000 $ 9,000 $ 10,000
PW of benefit $ 7,330 $4,700 $ 8,730 $1, 340 $9,000 $ 9, 500
1.83 2.35 1.46 1.34 1.00 0.95
