Answer 1

To find the mileage per gallon of Peri's car, we need to divide the distance she drove by the amount of gas she used:

Mileage per gallon = distance ÷ gas used

For Peri's car, the mileage per gallon is:

Mileage per gallon = 400 ÷ 31
Mileage per gallon = 12.9032

Rounding to the nearest tenth, we get:

Mileage per gallon = 12.9

Therefore, the mileage per gallon of Peri's car is 12.9.
