A toll road has been opened between two cities. Your business is in one of these cities. You need to travel between the two cities regularly as you have a customer to whom you deliver goods has their factory in the other city. The distance between you and your customer is 102 miles via the shortest free road and 95 miles via the new toll road. Determine the economic advantage of using the toll road, if any, given the following conditions:

Toll cost 5.50 m.u. Driver cost 12.50 m.u./hour Average driving speed is 60 mph via the toll road and 50 mph via the

free road

The estimated average cost of operating the truck per mile is 0.18 m.u./mile via the toll road and 0.20 m.u./mile via the free road

What interest rate should we choose?What interest rate should we choose? At least the government’s cost of borrowing moneyAt least the government’s cost of borrowing money ““To maintain public and private expenditures on a comparative basis, it

seems logical that the interest rate selected should represent the opportunity forgone when taxes are paid. That is, the interest rate should reflect the rate that should have been earned if the funds had not been removed from the private sector.”
