Washington Air Company is considering the purchase of a helicopter for connecting services between the company's base airport and the new intercounty airport being built about 30 miles away It is believed that the chopper will be needed only for six years until the Rapid Transit Connection is phased in. The estimates on two types of helicopters under consideration, the Whirl 2B and the ROT 8. are given below:

The Whirl 2B

First Cost $95,000

Annual Maintenance $3,000

Salvage Value $12,000

Useful Life 3 years

The ROT 8

First Cost $120,000

Annual Maintenance $9,000

Salvage Value $25,000

Useful Life 6 years

Assuming that the Whirl 2B will be available in the future with identical costs, what is the annual cost advantage of selecting the ROTX? (Use an interest rate of 10%.)
