A company makes a product that sells for $80 per unit. Variable expenses are $40.00 per unit, and fixed expenses total $200,000 per year. Its operating results for last year were as follows: Sales $ 2,080,000 Variable expenses 1,040,000 Contribution margin 1,040,000 Fixed expenses 200,000 Net operating income $ 840,000 The company president wants to add new features to the product, which will increase the variable expenses by $1.90 per unit. She thinks that the new features, combined with some increase in marketing spending, would increase this year's sales by 25%. How much could the president increase this year's fixed marketing expense and still earn the same $840,000 net operating income as last year
