120 people attended the baseball game. Adults cost $6 and students cost $4 to attend the game. The game raised $600 from the attendance. How many students attended the game?

  1. John

    A + S=120
    6A +4S = 600

    Use substitution A= 120-S


    6(120-S) + 4s = 600

    720 -6S + 4S = 600
    720 -2S = 600

    Can you finish from here?

  2. Bosnian

    a = numbers of adults

    s = number of students


    120 people attended the baseball game mean:

    a + s = 120


    Adults cost $6 and students cost $4 to attend the game.

    The game raised $600 from the attendance mean:

    a * &6 + s * $4 = $600

    OR

    6 a + 4 s = 600


    Now you must solwe system:

    a + s = 120

    6 a + 4 s = 600

    Try to solve this system.


    The solutions are:

    a = 60 , s = 60


    Proof:

    a + s = 60 + 60 = 120

    6 a + 4 s = 6 * 60 + 4 * 60 = 360 + 240 = 600
