Fast growth in the population of the city of Orlando and surrounding counties, Orange County in particular, has resulted in insurmountable traffic congestion. The county has few places to turn for extra money for road improvements except to new taxes. County officials have said that the money they receive from current taxes is insufficient to widen over$-$crowded roads, improve roads that don$T^{TM}t$ meet modern standards, and pave dirt roads. State residents now pay $12$ cents in taxes on every gallon of gas. Four cents of that goes to the federal government, $4$ cents to the state, $3$ cents to the county in which the tax is collected, and $1$ cent to the cities. The county commissioner has suggested that the county get the money by tacking an extra penny$-$a$-$gallon tax onto gasoline, bringing the total federal and state gas tax to $13$ cents a gallon. This would add about $$2\mathrm{.}6$ million a year to the road$-$construction budget. The extra money would have a significant impact. With the additional revenue, the county could sell a $$24$ million bond issue. It would then have the option of spreading that amount among many smaller projects or concentrating on a major project. Assuming that voters would approve a higher gas tax, the county engineers were asked to prepare a priority list outlining which roads would be improved with the extra money. The road engineers also computed the possible public benefits associated with each road$-$construction project; they accounted for possible reduction in travel time, a reduction in the accident rate, land appreciation, and savings in operating costs of vehicles.
