Martin Enterprises needs someone to supply it with $128,000$ cartons of machine screws per year to support its manufacturing needs over the next five years, and you$$ve decided to bid on the contract. It will cost you $$925,000$ to install the equipment necessary to start production; you$$ll depreciate this cost straight$-$line to zero over the project$$s life. You estimate that, in five years, this equipment can be salvaged for $$94,000.$ Your fixed production costs will be $$500,000$ per year, and your variable production costs should be $$17\mathrm{.}65$ per carton. You also need an initial investment in net working capital of $$96,000.$ Assume your tax rate is $23$ percent and you require a return of $12$ percent on your investment.

a$.$

Assuming that the price per carton is $$26\mathrm{.}60,$ what is the NPV of this project? $($Do not round intermediate calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

b$.$ Assuming that the price per carton is $$26\mathrm{.}60,$ find the quantity of cartons per year that you can supply and still break even. $($Do not round intermediate calculations and round your answer to the nearest whole number, e$.$g$.,32.)$

c$.$ Assuming that the price per carton is $$26\mathrm{.}60,$ find the highest level of fixed costs you could afford each year and still break even. $($Do not round intermediate calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
