Y total cost,

A fixed element
B variable element

Data :

Use above data to calculate A and B

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
