You can put this solution on YOUR website!
Take 40% of $210 to get \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0.40*210 = 84\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "They want to make a profit of $84. Add this amount onto the initial cost: 210+84 = $294\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So they need to sell it at $294. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since they said that's wrong, there is either a typo in the original question or in the answer (or maybe the computer is misreading). Also, be sure to write \"S=210+.40(210)\" and NOT \"S=210-.40(210)\". Notice how there's a plus sign in the correction.
