There is a road between the suburbs and downtown. The road is congested at rush hour. If 162 people use the road at rush hour, the trip takes 46 minutes. If one additional person enters the road, everyone has to slow down and the trip now takes 47 minutes. People value their time at $6 per hour (that is, $0.10 per minute). For simplicity, ignore all of the costs of using the road other than the cost of time. The total social cost of 162 people using the road at rush hour is $D. (Round your response to one decimal place.)
