Question 726508: (c) A coffee store will start selling a mix of two kinds of coffee: Kona and Mexican Organic. The price of Kona coffee is $7.50 per pound and the price of Mexican Organic coffee is $8.30 if they are sold separately. The store wants the price of the mix to be $8.00 per pound. How many pounds of each kind should be used to prepare 160 pounds of the mix?
You can put this solution on YOUR website! 7.50x+8.30(160-x)=8.00*160
7.50x+1328-8.30x=1280
-.8x=1280-1328
-.8x=-48
x=-48/-.8
x=60 pounds of Kona coffee is used.
160-60=100 pounds of Mexican coffee is used.
Proof:
7.50*60+8.30*100=8.00*160
450+830=1280
1280=1280
