A company makes a product that sells for $80 per unit. Variable expenses are $40.00 per unit, and fixed expenses total $180,000 per year. Its operating results for last year were as follows: Sales $2,000,000 Variable expenses 1,000,000 Contribution margin 1,000,000 Fixed expenses 180,000 Net operating income $ 820,000 The company president wants to add new features to the product, which will increase the variable expenses by $1.80 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 $820,000 net operating income as last year
