Question

You plan to take a 1150​-mile trip in your​ car, which averages 20 miles per gallon. How many gallons of gasoline should you expect to​ use

Answer 1

57.5 or 58

Explanation:

1150 = 20x

Divide both sides by 20 to get 57.5

To be proper, you should say that 58 gallons will be used.

It all depends on the teacher, but I know that mine used to tell me to round these types of things up. If you would like to be more exact, just put 57.5 gallons.
