1. The CVP graph can be plotted using the three steps outlined in the text. The graph appears on the next page.

Step 1. Draw a line parallel to the volume axis to represent the total fixed expense. For this company, the total fixed expense is \$12,000.

Step 2. Choose some volume of sales and plot the point representing total expenses (fixed and variable) at the activity level you have selected. We’ll use the sales level of 2,000 units.

Fixed expenses
\$12,000

Variable expenses (2,000 units × \$24 per unit)
48,000

Total expense...
