With the traditional algebraic solution method (very slow; but you should understand it):

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:

3.60%28x%29%2B2.70%2860-x%29+=+3.00%2860%29

It's basic algebra; I leave it to you to solve the equation and find the answer.

A much faster path to the answer:

$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.

Peanuts price dollars per pound, L=2.7
Walnuts price dollars per pound, H=3.6
Mixture quantity, pounds M=60
Mixture price, T=3

Question asks for quantity pounds of peanuts, p.
The quantity of walnuts would be M-p.
