<PRE><B>Question 328754</B>
how many gallons each of 25% alcohol and 35% alcohol should be mixed to get 10 gallons of 32% alcohol?
------------
Equation:
alcohol + alcohol = alcohol
0.25 x + 0.35(10-x) = 0.32*10
==================================
Multiply thru by 100 to get:
25x + 35*10 - 35x = 32*10
-10x = -3*10
x = 3 gallons (amt. of 25% alcohol needed in the mixture)
-----------
10-x = 7 gallons (amt. of 35% alcohol needed in the mixture)
==========================
Cheers,
Stan H.
