Question 137108: Susan wants to prepare 25 lbs. of mixed nuts worth $1.74 per pound by using walnuts valued at $1.30 per lb and cashews valued at $2.30 per lb. How many pounds of each should be used to ensure no change in profit. Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! 25*1.74=2.30X+1.30(25-X)
43.50=2.30X+32.50-1.30X
43.50-32.50=2.30X-1.30X
11=X POUNDS OF 2.30 CASHEWS.
25-11=14 POUNDS OF WALNUTS.
PROOF
25*1.74=2.3*11+1.3*14
43.50=25.3+18.2
43.50=43.50
