Question

Chad-Tyler Migkins · Accepted Answer

Final Answer : D, Explanation :  Since each lane costs $10 million per mile, a three-lane highway would cost $30 million per mile. The question asks for the total benefit, not cost, of a three-lane highway. Therefore, the answer must be $30 or more million per mile, as having multiple lanes can increase the efficiency of the highway and potentially lead to economic benefits such as reduced travel times and increased productivity.
