E.2. A shuttle bus service is proposed between downtown and the airport, and you are asked to find the rate of retum, given the data below. cost of shuttle bus new - $150,000 life of shuttle bus = 120 months resale value at EOM 120 - $50,000 O&M cost = $2,000/month gradient in O&M - $20/month/month periodic overhaul every 12 months (first at EOM 7. last at EOM 115) = $5,000 at EOM 7 gradient in periodic overhaul = 1%/month compounded anticipated income = $5,800/month E.2.
