Let $\"+x+\"$ = ounces of raisins to put in mixture
\n" ); document.write( " $\"+1.2%2A14+=+16.8+\"$ = cost of the peanuts in mixture
\n" ); document.write( " $\"+.7x+\"$ = cost of raisins in mixture
\n" ); document.write( "--------------------------------
\n" ); document.write( " $\"+%28+16.8+%2B+.7x+%29+%2F+%28+14+%2B+x+%29+=+1.05+\"$
\n" ); document.write( " $\"+16.8+%2B+.7x+=+1.05%2A%28+14+%2B+x+%29+\"$
\n" ); document.write( " $\"+16.8+%2B+.7x+=+14.7+%2B+1.05x+\"$
\n" ); document.write( " $\"+.35x+=+2.1+\"$
\n" ); document.write( " $\"+x+=+6+\"$
