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

57.5 or 58

Step-by-step 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.
