Consider a four-year project with the following information: initial fixed asset investment = $625,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $51; variable costs = $39; fixed costs = $300,000; quantity sold = 121,000 units; tax rate = 23 percent. a. What is the degree of operating leverage at the given level of output? (Do not round intermediate calculations and round your answer to 4 decimal places, e.g., 32.1616.) b.
