Bayview's growth is constrained by mountains on one side and the bay on the other. A bridge across the bay is planned, but which plan is best? It can be built with a single deck to meet the needs of the next 20 years, or it can be built with two decks to meet the needs of the next 50 years. The piers can also be built to support two decks, but with only one deck being built now. Building it all now will cost $160M, and leaving the top deck for later will save $40M. Building that top deck later will cost $70M, including the cost of traffic disruption. A single-deck bridge will cost $100M now and S115M in 20 years. Deck maintenance is $1.4M per year per deck. Pier maintenance is $1.2M per year per bridge. If the interest rate is 6%, which design should be built? If the two-deck bridge is built immediately, dedicated lanes for buses, carpools, and bicycles can be added. To evaluate this use economically, estimate the cost of the underused capacity for the bridge

the answer is true.  i do believe this is the answer because of the amount of wrecks people get into each year.  if you double this with avoiding those so said wrecks, that would make you a "skilled" driver.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
