    Answer:

    #_cars = 7

    Explanation:

    For this exercise let’s start by finding the total number of students

              #_students = 12 +15

              #_students = 27

    Now we can use a direct proportion relationship or rule of three. If 4 students drive, how many cars for 27 students?

              #_cars = 27 (¼)

              #_cars = 6.75

    the number of cars must be an integer therefore the correct answer is

             #_cars = 7
