At an output level of 8,000 units, you have calculated that the degree of operating leverage is 1.90. The operating cash flow is $62,000 in this case. Ignore the effect of taxes. What will be the new degree of operating leverage for output levels of 9,000 units and 7,000 units? (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) DOL at 9,000 units? DOL at 7,000 units?
