Question 428669: A yogurt company blends regular yogurt that is 4% fat with its no-fat yogurt to obtain low-fat yogurt that is 2% fat. How many pounds of non-fat yogurt must be mixed to obtain 80 pounds of low-fat yogurt?
Answer by htmentor(1343) (Show Source): You can put this solution on YOUR website!
2% fat means 0.02*80 = 1.6 pounds fat
Let x = the number of pounds of 4% fat yogurt
Since we need to end up with 1.6 pounds of fat, we can write
0.04*x = 1.6 -> x = 40 pounds
Therefore, we need 40 pounds of 4% fat and 40 pounds of no-fat yogurt.
