Question 176847

{{{10000 =  800P}}}–{{{7P^2}}}


{{{7P^2    -   800P   +   10000   =   0}}}
(7P   -  100 )(P    -   100)     =     0
{{{P =(100/7)}}}(<$50)    or      P   =  100


Since we’re told that the price must be greater than $50, we have to reject {{{P =(100/7)}}}. Therefore, the correct choice is a price of $100.
