Extra lean ground beef (16% fat) is served in the cafeteria. The kitchen has 8 lbs. of regular ground beef (30% fat) on hand. How many extra lean ground beef (12% fat) must be purchased and added to the regular ground beef to obtain the correct fat content?
-------
Equation:
fat + fat = fat
0.30*8 + 0.12x = 0.16(8+x)
------
30*8 + 12x = 16*8 + 16x
4x = 14*8
x = 28 lbs (amt of 12% ground beef to add)
