We are evaluating a project that costs $$1\mathrm{.}68$ million, has a six$-$year life, and has no salvage value. Assume that depreciation is straight$-$line to zero over the life of the project. Sales are projected at $90,000$ units per year. Price per unit is $$37\mathrm{.}95,$ variable cost per unit is $$23\mathrm{.}20,$ and fixed costs are $$815,000$ per year. The tax rate is $21$ percent, and we require a return of $11$ percent on this project.

a$.$

Calculate the base$-$case cash flow and NPV$.($Do not round intermediate calculations and round your answers to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

b$.$ What is the sensitivity of NPV to changes in the sales figure? $($Do not round intermediate calculations and round your answer to $3$ decimal places, e$.$g$.,32\mathrm{.}161.)$

c$.$ If there is a $500-$unit decrease in projected sales, how much would the NPV change? $($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$.,32\mathrm{.}16.)$

d$.$ What is the sensitivity of OCF to changes in the variable cost figure? $($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$.,32\mathrm{.}16.)$

e$.$ If there is a $$1$ decrease in estimated variable costs, how much would the increase in OCF be$?($Do not round intermediate calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
