<PRE><B>Question 309711</B>
Deep thought granola is 25% nuts and dries fruit. 
Oat Dream Granola is 10% nuts and dried fruit. 
How much of deep thought and how much of oat dream should 
be mixed to form a 20-lb batch of granola that is 
19%nuts and dried fruit?
-----------------
Equation:
0.25D + 0.10(20-D)) = 0.19*20
------------------
Multiply thru by 100 to get:
25D + 10*20 - 10D = 19*20
15D = 9*20
D = 4 lb (amt of 25% needed in the mix)
Since D + G = 20, G = 16 lb (amt of 10% needed in the mix)
