Question 1105613
A very routine mixture exercise question.


x of $15/kg cashews
100-x of $12/kg walnuts


{{{15x+12(100-x)=13.20*100}}}
Find x and evaluate 100-x.


STEPS

{{{15x+1200-12x=100(13.20)}}}
{{{3x+1200=100(13.20)}}}
{{{3x=(13.2)(100)-(12)(100)}}}
{{{3x=(1.2)(100)}}}

{{{3x=120}}}
{{{highlight(x=40)}}}-----------kilograms of the cashews, $15 per kg


{{{100-x=highlight(60)}}}--------kilograms of the walnuts, $12 per kg
