You have been asked to analyze three technology companies and have been provided with the following information on the companies:

$\backslash$table$[[,\backslash$table$[[$Primary$],[$shares$],[$outstanding$]],$Price$/$share$,$Net Income,$\backslash$table$[[$Number of$],[$Options$],[$Outstanding$]],\backslash$table$[[$Value per$],[$option$]]],[$Zap Tech,$100,$$$20,$$$100,10,$$$10\mathrm{.}00$ I need to know how to use this adat to calculate the chaeapest $-$ seems like the answwer provided has a typo in step $1$ calculation of EPS for LoSoftware $-$ can you explain that step? TIt should be $$20/80-$ which means all of the stocks have the same P$/$E ratio? What other ration can be used to determine the cheapest?

I thought enterprise value was calculated by adding back debt $-$ you used net income. Can you explain? Thanks
