Question

Stan Moneymaker needs 16 gallons of gasoline to top off his automobile's gas tank. If he drives an extra eight miles (round trip) to a gas station on the outskirts of town, Stan can save $0.12 per gallon on the price of gasoline. Suppose gasoline costs $2.90 per gallon and Stan's car gets 25 mpg for in-town driving. Each mile that Stan drives creates one pound of carbon dioxide. Each pound of CO2 has a cost impact of $0.03 on the environment.

What are Stan's savings per mile for the eight mile extra trip, including the effect of environmental costs? Stan's savings are $_ per mile. (Round to four decimal places.)

Should Stan make the trip to get less expensive gasoline? Choose the correct answer Yes No
