Question 1102213
{{{system(x+y=28,25x+50y=30*28)}}}

-

{{{5x+10y=6*28}}}
{{{5(28-y)+10y=6*28}}}
{{{5*28-5y+10y=6*28}}}
{{{5y=6*28-5*28}}}
{{{5y=28}}}
{{{y=28/5}}}
{{{highlight_green(y=5&3/8)}}}-------grams of the 50% protein ingredient.  Use this to find x.





--------------(THIS WAS WRONG)----------------------------------------------


{{{system(x+y=28,30x+50y=25*28)}}}


{{{30x+50(28-x)=25*28}}}----simplify, solve for x, and evaluate y.  x is for the 30% protein, and y is for the 50% protein ingredients.
