: Planter's Peantut Co. wants to mix 20 lbs of peanuts worth $3 a pound with cashews worth $5 a pound in order to make an experimental mix worth $3.50 a pound. How many pounds of cashews should be added to the peanuts? This question is from textbook

Let us suppose that 20 pounds of peanuts is mixed with 'x' pounds of cashew.

Cost of 20 lbs. of peanuts = $(3x20) = $60.
Cost of cashew nuts = $5 per pound.
So cost of 'x' pounds of cashew = $5x.
So the cost of the mixture of 20 lbs. of peanut and 'x' lbs. of cashew = $(60+5x).
In other words cost of (20 + x) lbs. of the mixture = $(60+5x).
So, cost of each pound of the mixture = $.
Given, the price of this mixture is $3.5 per pound.

So,

or x = 6.67 (approx)

So 6.67 lbs. of cashew is to be added.
