he president believes that a $6,700 increase in the monthly advertising budget, combined with an intensified effort by the sales staff, will result in an $85,000 increase in monthly sales. If the president is right, what will be the effect on the companys monthly net operating income or loss? (Use the incremental approach in preparing your answer.)
