    Ignore the bit about the regression equation, you can use it if you want to but it's basically the high/low technique.

    High 13,500 unit 79,500 cost
    Low 8,000 units 52,000 cost

    Diff 5,500 units 27,500 cost. Unit cost (ie variable element) = 5

    Then plug that back into any of the known levels of production:

    8,000 units x 5 = 40,000 variable
    total cost 52,000
    so fixed cost is the difference, 12,000

    Try it any of the 3 levels of production, it will work
