What is the first step?
To look for the highest and lowest levels of activity
What causes the cost to happen?
The activity
What is the second step?
To work out the difference in the highest and lowest level of activity, and their corresponding cost
What is the difference between the highest and lowest level of activity?
Variable cost
How do you then work out the variable cost?
Divide the cost by the level of activity
Once we have the value of the variable cost, what do we do?
Substitute the lower activity, cost and variable cost all into the equation of a line, y = mx + c. This gives us the fixed cost
