Ziggy's Famous Yogurt blends regular yogurt tha is 3% fat with itsno-fat yogurt to obtain low-fat yogurt that is 1% fat. How manypounds of regular yogurt and how many pounds of no-fat yogurtshould be mixed to obtain 60 pounds of low-fat yogurt. - This problem can be solved in two stages. First establish theratio required to make low-fat. Then multiply to find the amountsrequired to make 60 lb of it. First: Establish the ratio. Try picking numbers. Forpercents, always start with 100 as the number. Say you have 100 lbof 3%, how much fat would be in it? Obviously 3 lb. If you added 200 lb of no-fat yog, you'd now have 300 lb of yogwith 3 lb of fat, which is 1% fat yog. Therefore we need a ratio of 2:1 (2 lb of no fat to every 1 lb offat) Adding 2 and 1 gives us 3. Divide the required 60 lb into threeparts of 20 lb each. 40 lb will be no-fat and 20 lb will be the 3%fat type.
