Question 304360: I have to figure out how much no fat yogurt should be mixed with regular yogurt to obtain 60 pounds of low fat yogurt.
I have 3% fat yogurt blends with no-fat yogurt that yields a 1%low fat yogurt.
I know that x60 is what I need to determine.
.03x is the 3%, .01 is the 1% which gives me 4% total lowfat yogurt. Then I divided that into the 60 needed and I came up with 17 pounds.
