Answer:
$4.14
Step-by-step explanation:
FV: Future value; PV: Present Value; i/r: Interest rate
n = 5 years = 5x12 = 60 months
i/r = 7.5% / year = 0.625%/month (compounded monthly)
FV = $30m (in 5 years)
PV = 0
PMT (Toll receipts per month) = ?
By inputing all these information into a financial calculator,
we have PMT = $413,638.46
Required Toll receipts per vehicle = $413,638.46 / 100,000 = $4.14
