A company decided to develop low$-$cost photo$-$voltaic solar$-$energy cells. It decided on two

development choices: a fully automatic line for $$800,000$ capable of producing $200,000$ cells$/$year for

a profit of $$1/$cell$,$ or a semi$-$automatic line for $$500,000$ capable of producing $120,000$ cells$/$year for a

profit $$1/$cell$.$ It is estimated that both lines will last for five years and will have a book value at the

end of the five years of $10$ percent. Assume both lines will be working to $100$ percent capacity. You

are the PM for development. Please make all calculations with or without taxes.

Show the ROI calculations for both machines, based on five$-$year life, $10$ percent book value, and

$33$ percent taxes when applicable.
