You can put this solution on YOUR website!
You can set the equation this way: Let x = the amount of caramel required.\r
\n" ); document.write( "\n" ); document.write( "\"5%280.80%29+%2B+x%282.40%29+=+%285%2Bx%29%281.40%29\" Simplify and solve for x.\r
\n" ); document.write( "\n" ); document.write( "\"4+%2B+2.40%28x%29+=+7+%2B+1.40%28x%29\" Subtract 1.40(x) from both sides.\r
\n" ); document.write( "\n" ); document.write( "\"4+%2B+x+=+7\" Subtract 4 from both sides.\r
\n" ); document.write( "\n" ); document.write( "\"x+=+3\"\r
\n" ); document.write( "\n" ); document.write( "3 lbs of caramel are needed. \r
\n" ); document.write( "\n" ); document.write( "Check:\r
\n" ); document.write( "\n" ); document.write( "\"5%28.80%29+%2B+3%282.40%29+=+%285%2B3%29%281.40%29\"
\n" ); document.write( "\"4+%2B+7.20+=+8%281.40%29\"
\n" ); document.write( "\"11.20+=+11.20\" Ok.
\n" ); document.write( "
\n" );
