Question 1179748


{{{R = m^2-95m-500}}}

 break even happens when {{{R=0}}}

{{{ m^2-95m-500=0}}}....factor

{{{ m^2+5m-100m-500=0}}}

{{{ (m^2+5m)-(100m+500)=0}}}

{{{ m(m+5)-100(m+5)=0}}}

{{{(x -100)(x + 5)=0}}}

need only positive solution 


{{{x=100}}}


answer: {{{100}}} liters of the acid solution should it manufacture to break even
