<PRE><B>Question 205467</B>
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 = {{{.6/.03}}}
x = 20 lb of 3% stuff required
then
60 - 20 = 40 lb of no fat (0%)</PRE>
