 Question 389642: Here's another one...*smiles* "Egg nog is made by mixing eggs, cream, milk and sugar together. The recipe calls for 3% butterfat milk. Whole milk contains 4% butterfat and skim milk contains 0% butterfat. How much skim milk should be added to 32oz of whole milk to obtain a mixture that is 3% butterfat?" I got 10.666666666666667 ounces...? And then the table asks us to list the amount in ounces (whole milk: 32oz...skim milk: x...mixture: x+32) and the amount of non fat for the 96% non fat (whole milk), the 100% non fat (skim milk) and the 97% non fat (mixture)... What do they mean list the amount of non fat...? Do they mean in equation form like... whole milk is .04*32=1.28 So 32oz-1.28= 30.72oz non fat...? Thanks in advance for all of your help! *smiles*Answer by ptaylor(2048)   (Show Source): You can put this solution on YOUR website!Let x=amount of skim milk that needs to be added to the whole milk Now we know that the amount of pure butterfat that exists before the mixture takes place (0.04*32) has to equal the amount of pure butterfat that exists after the mixture takes place (0.03(32+x)). So our equation to solve is: 0.04*32=0.03(32+x) simplify 1.28=0.96+0.03x 0.03x=1.28-0.96=0.32 x=10.666666666666666666666666667 SAME AS YOUR SOLUTION GOOOOOOOOD WORK!!!!!!!!!!!!!!!!! OOOOOOOOOOOOOOOOPs there's more: Whole Milk---32 oz Skim milk-----10.66666666667 oz Mixture-------42.6666666667 oz What do they mean list the amount of non fat...? Do they mean in equation form like... I believe that they want you to list the amount (in terms of ounces)of the non-fat components just like you are doing. Hope this helps----ptaylor
