You are considering a new product launch. The project will cost $$2,350,000,$ have a four$-$year life, and have no salvage value; depreciation is straight$-$line to zero. Sales are projected at $330$ units per year; price per unit will be $$19,600,$ variable cost per unit will be $$14,000,$ and fixed costs will be $$720,000$ per year. The required return on the project is $10$ percent, and the relevant tax rate is $21$ percent.

b$.$ Evaluate the sensitivity of your base$-$case NPV to changes in fixed costs. $($A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

c$.$ What is the cash break$-$even level of output for this project $($ignoring taxes$)?($Do not round intermediate calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

d$-1.$ What is the accounting break$-$even level of output for this project? $($Do not round intermediate calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

d$-2.$ What is the degree of operating leverage at the accounting break$-$even point? $($Do not round intermediate calculations and round your answer to $3$ decimal places, e$.$g$.,32\mathrm{.}161.)$
