<PRE><B>Question 235038</B>
regular yogurt that is 3%fat and 1% fat yogurt.
 How many pounds of regular yogurt and how many pounds of no fat yogurt would have to be mixed to obtain 60 pounds of low-fat yogurt.
;
Assume that he low fat stuff is 1%
:
Let x = amt of 3% stuff
The resulting amt is to be 60 lb, therefore
(60-x} = amt of no fat (0%)
:
Write an amt of fat equation
.03x + 0(60-x) = .01(60)
which is
.03x = .01(60)
.03x = .6
x = {{{.6/.03}}}
x = 20 lb of 3% stuff
then
60 - 20 = 40 lb of no-fat</PRE>
