<PRE><B>Question 197731</B>
The pineapple juice comes in two concentrated forms, 22% and 60% pineapple juice, which must be combined into a solution that can be mixed with the orange juice. If 60 gallons of 22% juice is used, how many gallons of the 60% juice must be used to obtain a 50% pineapple juice solution?
------------------------------------------------------------
Equation:
pineapple + pineapple = pineapple
0.22*60 + 0.60x = 0.50(60+x)
22*60 + 60x = 50(60+x)
22*60 + 60x = 50*60 + 50x
10x = 28*60
x = 28*6
x = 168 gallons (amt. of 60% juice that must be added)
