Atoll bridge across mississippi river is being considered as a replacement for the current i-40 bridge linking tennessee to arkansas. because this bridge, if approved, will become a part of the u. s. interstate highway system, the b-c ratio method must be applied in the evaluation. investment cost of the structure are estimated to be $17,000,000 and $325,000 per year in operating and maintenance costs are anticipated. in addition, the bridge must be resurfaced every fifth year of its 30-year projected lie at a cost of $1,250,00per occurrence (no resurfacing cost in year 30). revenues generated from the roll are anticipated to be $2,500,000 in its first year of operation, with a projected annual rate of increase of 2.25% per year due to the anticipated annual increase in traffic across the bridge. assuming zero market (salvage) value for the bridge at the end of 30 years and marr 10% per year, should the toll bridge be constructed?

The price of trade suppose that portugal and sweden both produce rye and wine. portugal's opportunity cost of producing a bottle of wine is 4 bushels of rye while sweden's opportunity cost of producing a bottle of wine is 10 bushels of rye. by comparing the opportunity cost of producing wine in the two countries, you can tell thatportugal/sweden has a comparative advantage in the production of wine.andportugal/sweden has a comparative advantage in the production of rye. suppose that portugal and sweden consider trading wine and rye with each other. portugal can gain from specialization and trade as long as it receives more rye for each bottle of wine it exports to sweden. similarly, sweden can gain from trade as long as it receives more bottles of wine for each bushel of rye it exports to portugal. based on your answer to the last question, which of the following prices of trade (that is, price of wine in terms of rye) would allow both sweden and portugal to gain from trade? a. 1 bushels of rye per bottle of wineb. 8 bushels of rye per bottle of winec. 9 bushels of rye per bottle of wined. 3 bushels of rye per bottle of wine
