You are evaluating a project for your company. You estimate the

sales price to be $$640$ per unit and sales volume to be $3,400$ units

in year $1$; $4,400$ units in year $2$; and $2,900$ units in year $3.$ The

project has a three$-$year life. Variable costs amount to $$440$ per

unit and fixed costs are $$270,000$ per year. The project requires an

initial investment of $$395,000$ in assets which will be depreciated

straight$-$line to zero over the three$-$year project life. The actual

market value of these assets at the end of year $3$ is expected to be

$$64,000.$ NWC requirements at the beginning of each year will be

approximately $20$ percent of the projected sales during the coming

year. The tax rate is $30$ percent and the required return on the

project is $8$ percent. What change in NWC occurs at the end of year

$1?$$$371,200$$$128,000$$$259,840$$$89,600$Please show work so I will know how to solve in future.
