The firm has two offices-one in Chicago and one in Minneapolis. The firm classifies the direct costs of consulting jobs as variable costs. A contribution format segmented income statement for the company's most recent year is given below: Office Total Company Chicago Sales. $450,000 100% 150,000 100% $300,000 100% 225,000 50% 45,000 30 0,000 60 225,000 50% 105,000 70 120,000 40 126,000 28% Variable expenses..

Compute the companywide break-even point in dollar sales. Also compute the break-even point for the Chicago office and for the Minneapolis office. Is the companywide break-even point greater than, less than, or equal to the sum of the Chicago and Minneapolis break even points? Why? 2. By how much would the company's net operating income increase if Minneapolis increased its sales by $75,000 per year? Assume no change in cost behavior patterns. 3. Refer to the original data. Assume that sales in Chicago increase by $50,000 next year and that sales in Minneapolis remain unchanged. Assume no change in fixed costs. a. Prepare a new segmented income statement for the company using the above format. Show both amounts and percentages b. Observe from the income statement you have prepared that the contribution margin ratio for Chicago has remained unchanged at 70% (the same as in the above data) but that the segment margin ratio has changed. How do you explain the change in the segment margin ratio
