Question 1203078
Mix 20% and 10% to have 1200 pounds of 15%;
That's reaching halfway between.

600 of EACH!


Some arithmetic to help,

x of the 20% protein
1200-x of the 10% protein

{{{20x+10(1200-x)=15*1200}}}


{{{20x-10x+10*1200=15*1200}}}

{{{(20-10)x=15*1200-10*1200}}}

{{{x=1200((15-10)/(20-10))}}}

{{{x=1200(5/10)}}}

{{{x=1200(1/2)}}}

{{{x=600}}}----------------you finish.
