    Answer:

    The correct answer is c) 48

    Step-by-step explanation:

    Let the number of students = y

    Let the number of benches = x

    From the first statement

    y = 4x – 12 (three empty benches * 4 students)

    From the second statement

    y = 3x + 3

    Substituting equation 2 into equation 1

    3x + 3 = 4x – 12

    Rearranging..

    x = 15

    Substituting the value for x in equation 2

    y = 3(15) + 3 = 48

    Hope it helps ^_^
