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 + 10(94-x) = 14*84}}}  |Having multiplied thru by 100
       12x = {{{4*84}}}
         x = 28 lb  of the 22%  and 62 lb of the 10%
