Yogurt blends regular yogurt that is 3% fat with its no fat yogurt to obtain
lowfat yogurt that is 1%. How many pounds of regular yogurt and how many pounds
of no fat yogurt should be mixed to obtain 60 pounds of low fat yogurt?
Let x = amt of 3% stuff
write am amt of fat equation, (amt of fat remains unchanged, the per cent changes)
.03x = .01(60)
.03x = .6
x = 20 lb of 3% stuff required
60 - 20 = 40 lb of no fat (0%)
