Its operating results for last year were as follows: Sales $1,080,000 Variable expenses 540,000 Contribution margin 540,000 Fixed expenses 200,000 Net operating income $340,000 The company president wants to add new features to the product, which will increase the variable expenses by $2.40 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 $340,000 net operating income as last year
