Suppose your family has 2 vehicles. one is a truck that gets 10 miles per gallon, and the other is a car that gets 30 miles per gallon. your family puts 10, 000 miles on the truck and 10,000 miles on the car each year. you would like to update one of your vehicles. if you get a new truck it will get at least 12 miles per gallon. if you get a new car, it will get 40 miles per gallon which vehicle should replace first if you want to save more energy or money on gas?
(a) simple math shows that updating your truck from 10 miles per gallon to 12 miles per gallon would result in a 20% increase in miles per gallon. updating your car from 30 miles per gallon to 40 miles per gallon would result in a 33% increase in miles per gallon. which vehicle should you update? (b) calculate how many gallons of gas your truck uses each year, and how many gallons of gas your car uses (c) calculate how many gallons of gas a truck that gets 12 miles per gallon will use, and how many gallons of gas a car that gets 40 miles per gallon will use
(d) now calculate how many gallons you will save in a many you will save if you update your car year if you update your truck and how (e) do you want to update your answer to part (a)? (f) (critical thinking) - this problem was pretty restricted in its analysis of possible actions what alternative actions would you recommend your family take?
