<PRE><B>Question 1019554</B>
A coffee wholesaler wants to blend a coffee containing 35% chicory with coffee containing 15% chicory to produce a 500-kilogram blend of coffee containing 18% chicory. How much of each type is required? 
--------
Equation:
chic + chic = chic
-----
0.35x + 0.15(500-x) = 0.18*500
-----------------------------
35x + 15*500 - 15x = 18*500
------
20x = 3*500
x = 75 lb (amt. of 35% coffee needed)
500-x = 425 lb (amt. of 15% coffee needed)
----------
