You can put this solution on YOUR website!
Let $\"+x+\"$ = ounces of mixture A to be added
\n" ); document.write( " $\"+.12x+\"$ = ounces of baking soda in mixture A
\n" ); document.write( " $\"+.25%2A130+=+32.5+\"$ = ounces of baking soda in mixture B
\n" ); document.write( "------------------------------------------------------
\n" ); document.write( " $\"+.12x+%2B+32.5+=+52+\"$
\n" ); document.write( " $\"+.12x+=+19.5+\"$
\n" ); document.write( " $\"+x+=+162.5+\"$
\n" ); document.write( "Add 162.5 ounces of mixture A
\n" ); document.write( "---------------------------------
\n" ); document.write( "check answer :
\n" ); document.write( " $\"+%28+.12x+%2B+32.5+%29+%2F+%28+x+%2B+130+%29+=+52%2F%28+x+%2B+130+%29+\"$
\n" ); document.write( " $\"+%28+19.5+%2B+32.5+%29+%2F+162.5+=+52%2F162.5+\"$
\n" ); document.write( " $\"+52%2F162.5+=+52%2F162.5+\"$
\n" ); document.write( " $\"+.32+=+.32+\"$
\n" ); document.write( "So you end up with a 32% mixture
\n" ); document.write( "( not required by problem )
