Final answer:
The car's mileage in miles per gallon can be calculated by finding the average miles per gallon of a group of cars. None of the given options match the calculated average exactly, but the closest option is C) 20 miles per gallon.
Step-by-step explanation:
The car's mileage in miles per gallon is determined by dividing the number of miles the car can travel by the amount of gasoline it consumes. To find the car's mileage in miles per gallon, we need to calculate the average fuel efficiency of the car. This can be done by finding the average miles per gallon of the 30 cars listed.
The average miles per gallon of the cars listed can be calculated by summing up all the miles per gallon ratings and dividing by the total number of cars. The sum of the miles per gallon ratings is 701, and there are 30 cars listed. Therefore, the average miles per gallon is 701 / 30 = 23.37 miles per gallon.
Since none of the answer options match the calculated average miles per gallon, there is no exact answer among the given options. The closest option to the calculated average is option C) 20 miles per gallon, but it is still slightly lower than the calculated average. Therefore, the most appropriate answer would be option C) 20 miles per gallon, but it is not an exact match.
