Question

Stan Moneymaker needs 14 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 $0.15 per gallon on the price of gasoline. Suppose gasoline costs $2.40 per gallon and Stan's car gets 27 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.)**

Answer #1

Gasoline amount that can be saved per gallon = 0.15$ per gallon

Total number of gallons required = 14

Amount saved on gasoline = 0.15*14 = 2.1$

Cost of environment per compound = 0.03$

Total number of compounds release = 8

Environmental cost = 0.03*8 = 0.24

Stan car gives = 27 miles per gallon

So for 8 miles stan uses how much amount of gasoline= (8/27) = 0.2963 gallons

Cost of gasoline = 2.40 per gallon

Amount spent to travel 8 miles = 0.2963*2.40 = 0.71112

Net amount saved = 2.1-0.24-0.71112 = 1.14888$

So total amount saved = 1.1489$ (approximately)

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...
