I know headquarters wants us to add that new product line, said Fred Halloway, manager of Kirsi Products East Division. But I want to see the numbers before I make a move. Our divisions return on investment (ROI) has led the company for three years, and I dont want any letdown. Kirsi Products is a decentralized wholesaler with four autonomous divisions. The divisions are evaluated on the basis of ROI, with year-end bonuses given to divisional managers who have the highest ROI. Operating results for the companys East Division for last year are given below: Sales $ 21,000,000 Variable expenses 13,400,000 Contribution margin 7,600,000 Fixed expenses 5,920,000 Net operating income $ 1,680,000 Divisional operating assets $ 5,250,000 The company had an overall ROI of 18% last year (considering all divisions). The companys East Division has an opportunity to add a new product line that would require an investment of $3,000,000. The cost and revenue characteristics of the new product line per year would be as follows: Sales $ 9,000,000 Variable expenses 65% of sales Fixed expenses $ 2,520,000 Required: Compute the East Divisions ROI for last year; also compute the ROI as it would appear if the new product line is added. (Do not round intermediate percentage values. Round your intermediate calculations and final answers to 2 decimal places. Omit the "%" sign in your response.)

Adding the new line would decrease the company's overall ROI. Adding the new line would increase the company's overall ROI.
