a) Just plug in x=60 to get: \"C%2860%29=%281.5%2A60%29%2F%28100-60%29=90%2F40=9%2F4=2.25\". So the cost is 2.25 million.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "b) Since we want the cost to be 5 million, we let \"C%28x%29=5\" and plug it in to get \"5=%281.5x%29%2F%28100-x%29\". Now we solve for 'x':\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"5=%281.5x%29%2F%28100-x%29\" Start with the given equation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"5%28100-x%29=1.5x\" Multiply both sides by 100-x.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"500-5x=1.5x\" Distribute.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"500=1.5x%2B5x\" Add 5x to both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"500=6.5x\" Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"500%2F6.5=x\" Divide both sides by 6.5 to isolate 'x'.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"76.9230769=x\" Divide\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now round to the nearest whole number to get \"x=77\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the percentage is 77% (to the nearest whole percentage)
\n" ); document.write( "
\n" );
