Final answer:
To determine monthly fuel consumption for a car that gets 18 miles per gallon and is driven 1000 miles per month, divide the total miles by the fuel efficiency to calculate the needed gallons of gasoline, which is approximately 55.56 gallons.
Step-by-step explanation:
Calculating Monthly Fuel Consumption
If you drive a car that averages 18 miles per gallon and you drive 1000 miles per month, you can calculate the number of gallons of gasoline needed each month.
To do this, simply divide the total monthly mileage by the car's fuel efficiency:
- Find the car's fuel efficiency, which is 18 miles per gallon.
- Divide the total monthly mileage, which is 1000 miles, by the car's fuel efficiency. This is written as 1000 miles / 18 miles per gallon.
- Perform the division to calculate the gallons needed. The calculation is 1000 / 18 ≈ 55.56.
Therefore, you would need approximately 55.56 gallons of gasoline to drive 1000 miles in a month with a car that has a fuel economy of 18 miles per gallon.
