You can
put this solution on YOUR website! 7. Consider again the car described in Exercise 6. On about what percentage of the trips will your gas mileage be above 43 miles per gallon?
We don't know what was described in "Exercise 6",

Post again telling us what "Exercise 6" was all about,
and then we'll be able to help you.
