To find the mileage per gallon of Peri's car, we need to divide the total miles driven by the total gallons of gas used.
Step 1: Calculate Peri's mileage per gallon.
Mileage = Total miles driven / Total gallons of gas used.
Peri drove 400 miles on 31 gallons of gas.
Mileage = 400 miles / 31 gallons = 12.903225806451613 miles per gallon.
Step 2: Round the mileage per gallon to the nearest tenth.
Rounded mileage per gallon = 12.9 miles per gallon.
Therefore, the mileage per gallon of Peri's car is approximately 12.9 miles per gallon.
To find the mileage per gallon of Peri's car, we need to divide the total distance she drove by the number of gallons she used.
Peri drove 400 miles on 31 gallons of gas. Therefore, we divide 400 by 31:
