Operating results for the companys East Division for last year are given below: Sales $ 23,600,000 Variable expenses 13,000,000 Contribution margin 10,600,000 Fixed expenses 8,594,000 Net operating income $ 2,006,000 Divisional operating assets $ 5,900,000 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 $2,980,000. The cost and revenue characteristics of the new product line per year would be as follows: Sales $ 8,940,000 Variable expenses 65% of sales Fixed expenses $ 2,521,080 1.
