Answer:
396 miles / 22 gallons = 18 miles per gallon
468 miles / 18 miles = 26 gallons of gasoline
What I did is I took the number of miles and divided it by the number of gallons to find how many gallons of gasoline were used per mile. Then I took that number of miles and divided 468 by it because that's the number of gallons we are trying to find. We ended up with 26 gallons of gasoline for 468 miles.
