    Set up a proportion to solve.

    If 6 tickets are for one club, meaning that the total amount of people in that club are 6.

    6/15 = 9/x

    Cross Multiply

    6*x = 6x

    9*15 = 135

    6x = 135

    Now we need to solve for x by isolating the variable.

    6x/6 = 135/6

    x = 135/6

    x = 22.50

    Answer: It will cost $22.50 for 9 members.
