1-a. Compute the companywide break-even point in dollar sales.
1-b. Compute the break-even point for the Chicago office and for the Minneapolis office.
1-c. Is the companywide break-even point greater than, less than, or equal to the sum of the Chicago and Minneapolis break-even points?

Explanation:

 1. The computation of the company wide break-even point in dollar sales is shown below:

Break even point = (Traceable fixed expenses + Common fixed expenses   ) ÷ (Profit volume Ratio)  

where,  

Contribution margin = Sales - Variable expenses

= $450,000 - $225,000

= $225,000

And, Profit volume ratio = (Contribution margin) ÷ (Sales) × 100

= ($225,000) ÷ ($450,000) × 100

= 50%

So, the company wide break even point in dollar sales is

= ($126,000 + $63,000) ÷ (50%)

= $378,000

b. For Chicago

Break even point = (Traceable fixed expenses) ÷ (Profit volume Ratio)  

where,  

Contribution margin = Sales - Variable expenses

= $150,000 - $45,000

= $105,000

And, Profit volume ratio = (Contribution margin) ÷ (Sales) × 100

= ($105,000) ÷ ($150,000) × 100

= 70%

So, the company wide break even point in dollar sales is

= ($78,000) ÷ (70%)

= $111,429

For Minneapolis

Break even point = (Traceable fixed expenses) ÷ (Profit volume Ratio)  

where,  

Contribution margin = Sales - Variable expenses

= $300,000 - $180,000

= $120,000

And, Profit volume ratio = (Contribution margin) ÷ (Sales) × 100

= ($120,000) ÷ ($300,000) × 100

= 40%

So, the company wide break even point in dollar sales is

= ($48,000) ÷ (40%)

= $120,000

c. The company wide break even point in sales dollars is $378,000 and the total is $111,429 + $120,000 = $231,429

So, the company wide break even point is greater than the  sum of the Chicago and Minneapolis break-even points due to the common fixed expenses
