at an output level of 18,200 units, you have calculated that the degree of operating leverage is 2.90. the operating cash flow is $59,500 in this case. ignore the effect of taxes. what will be the new degree of operating leverage for output levels of 19,000 units and 17,000 units? (do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
