You can put this solution on YOUR website! A candy distributor needs to mix a 10% fat-content chocolate with a 60% fat-content chocolate to create 200 kilograms of a 45% fat-content chocolate. How many kilograms of each kind of chocolate must they use?
------------------------------
fat + fat = fat
0.10x + 0.60(200-x) = 0.45*200
---------------------------------
10x + 60*200 - 60x = 45*200
-50x = -15*200
x = (3/10)*200
x = 60 kg (amt. of 10% needed)
200-x = 140 kg (amt. of 60% needed)
