srfoss said:Suppose you want to make mixture of peanuts and walnuts that costs $2.70 per pound. How many pounds of peanuts at $1.50 per pound should be mixed with 24 pounds of walnuts at $3.50 per pound? thank you for any help

If P = number of pounds of peanuts, and
24 + P = number of pounds of walnuts, - However here (24+P) is the total weight of the mixture not of walnuts alone.
your equation is correct, Subhotash.
But, we constantly emphasize the meaning of variables, and your equation has both P and p in it...

If so, shouldnt it be... (a+24)nuts * 2.70 (as pointed out by subhutosh earlier) thus reading, (a * 1.5 + 24 * 3.5) = (a + 24) * 2.70 (then solving for a)
