<PRE><B>Question 756323</B>
I have a 13% feed.
I want a 14% feed.
I can add a 32% booster.
What ratio of 32% booster do I need to increase my 13% to 14%?
I thought there was a cross pattern of multiplication for the formula.
-----------------
x = amount of 13%
y = amount of 32%
----
x*13 + y*32 = (x+y)*14
13x + 32y = 14x + 14y
18y = x
Mix 18 parts of 14% to 1 part of 32%
