. Darya's car averages 36 miles per gallon. How many gallons of gas will she need for a 480-mile trip? What is the cost of the gas she needs if gas costs $3.12 per gallon?
480 / 360 = 13.3333 gallons
13.33333 * 3.12 = $_________
To find how many gallons of gas Darya will need for her 480-mile trip, divide the total distance by the average miles per gallon of her car.
Number of gallons = Total distance / Average miles per gallon
Number of gallons = 480 miles / 36 miles per gallon
To solve this, we divide 480 by 36:
Number of gallons = 13.33 gallons (rounded to two decimal places)
Therefore, Darya will need approximately 13.33 gallons of gas for her 480-mile trip.
To find the cost of the gas, multiply the number of gallons needed by the cost per gallon.
Cost of gas = Number of gallons * Cost per gallon
Cost of gas = 13.33 gallons * $3.12 per gallon
To solve this, multiply 13.33 by 3.12:
Cost of gas = $41.54 (rounded to two decimal places)
Therefore, the cost of the gas she needs for her 480-mile trip is approximately $41.54.
