how many ounces of hamburger that is 75% lean must be mixed with hamburger that is 90% lean to get 65 ounces of hamburger that is 85% lean?
--------
Equation:
lean + lean = lean
0.75x + 0.90(65-x) = 0.85*65
------------------------------
75x + 90*65 - 90x = 85*65
-----------------------------
-25x = -5*65
x = (1/5)65
x = 13 ounces (amt. of 75% hamburger needed)
-------
65-x = 52 ounces (amt. of 90% hamburger needed)
