Hi,

some hamburger that is 22% fat and some that is 10% fat.

How many pounds of each should be mixed to make 84 lb of hamburger that is 14% fat

Let x and (94-x) represent the 22% amount and 10% amount respectively.

 22x+%2B+10%2894-x%29+=+14%2A84  |Having multiplied thru by 100

       12x = 4%2A84

         x = 28 lb  of the 22%  and 62 lb of the 10%
