45% protein and 20% protein
to make 2000 pounds of 35%

PERCENTAGE
SUPPLEMENT        QUANTITY      PROTEIN
   45                h            45h
   20               2000-h       20(2000-h)
-----------------------------------------
   35              2000         35*2000
</pre>
{{{highlight_green(45h+20(2000-h)=35*2000)}}}

{{{45h-20h+20*2000=35*2000}}}

{{{(45-20)h=35*2000-20*2000}}}

{{{highlight(h=(2000(35-20))/(45-20))}}}-----simplify, compute, and finish.

-


{{{h=2000((35-20)/(45-20))}}}

{{{h=2000(15/25)}}}

{{{h=2000(3/5)}}}

{{{h=(100*4*5*3)/5}}}

{{{highlight(h=1200)}}}


1200 pounds the 45%
800 pounds of the 20%
