Question 1135175
<br>
With the traditional algebraic solution method (very slow; but you should understand it):<br>
x pounds of walnuts at $3.60 per pound, plus (60-x) pounds of peanuts at $2.70 per pound, equals 60 pounds of mixture at $3.00 per pound:<br>
{{{3.60(x)+2.70(60-x) = 3.00(60)}}}<br>
It's basic algebra; I leave it to you to solve the equation and find the answer.<br>
A much faster path to the answer:<br>
$3.00 per pound is twice as close to $2.70 per pound as it is to $3.60 per pound ($3.60-$3.00 = $0.60; $3.00-$2.70 = $0.30), so use twice as many peanuts as walnuts.  So 40 pounds of peanuts and 20 pounds of walnuts.
