A car used 15 gallons of gasoline and traveled a total distance of 350 miles. The car's fuel efficiency is 25 miles per gallon on the highway and 20 miles per gallon in the city. Which equation can you solve to find h, the number of gallons that were used on the highway? A. 350=25(15-h)+20h B. 25h+20(15-h)=350 C. 350= (25+20/2)h D. 15= 350/25h + 350/20h

    There had better by an h*25 in the correct answer. What else can we use to decide?

    You didn't answer my question. I see a 25h in all four. We'll need to think up other structures, such as (15-h)20. Where do you see that?

    Maybe the units will help. Gallons * (Miles per Gallon) = Miles
