Let \"x\" = quarts of grape juice needed
\n" ); document.write( "\"1.2x\" = cost of grape juice needed
\n" ); document.write( "\".9%2A3+=+2.7\" = cost of apple juice used
\n" ); document.write( "In words:
\n" ); document.write( "(cost of all juice)/(total quarts of all juice) = $1/(1 quart)
\n" ); document.write( "\"%281.2x+%2B+2.7%29%2F%28x+%2B+3%29+=+1\"
\n" ); document.write( "\"1.2x+%2B+2.7+=+x+%2B+3\"
\n" ); document.write( "\".2x+=+.3\"
\n" ); document.write( "\"x+=+1.5\" quarts of grape juice needed
\n" ); document.write( "
