Final answer:
Jason paid approximately $1.1446 per gallon of gas on his recent fill-up by determining the total miles driven, calculating the gallons used based on his car's fuel efficiency, and then dividing the total cost by the gallons used.
Step-by-step explanation:
Jason needs to calculate the price he paid per gallon of gas on his recent fill-up. To do this, we need to determine how many gallons he used during his trip. First, we subtract the starting odometer reading from the ending reading to find the total miles driven: 43,156.8 - 42,676.1 = 480.7 miles. Next, we calculate the gallons used by dividing the miles driven by the car's fuel efficiency: 480.7 miles ÷ 32 miles/gallon = 15.021875 gallons. Now, we can find the cost per gallon by dividing the total cost of the fill-up by the number of gallons: $17.20 ÷ 15.021875 gallons ≈ $1.1446 per gallon.
