Substitute x=2,7,9,11 into the problem and solve for p like so:
\n" ); document.write( " $\"P=-x%2F2%2B75\"$
\n" ); document.write( "When x=2
\n" ); document.write( " $\"p=-2%2F2%2B75\"$
\n" ); document.write( " $\"p=-1%2B75\"$
\n" ); document.write( "p=$74
\n" ); document.write( "When x=7
\n" ); document.write( " $\"p=-7%2F2%2B75\"$
\n" ); document.write( " $\"p=-7%2F2%2B150%2F2\"$
\n" ); document.write( " $\"p=%28-7%2B150%29%2F2\"$
\n" ); document.write( " $\"p=143%2F2\"$
\n" ); document.write( "p=$71.50
\n" ); document.write( "When x=9
\n" ); document.write( " $\"p=-9%2F2%2B75\"$
\n" ); document.write( " $\"p=-9%2F2%2B150%2F2\"$
\n" ); document.write( " $\"p=%28-9%2B150%29%2F2\"$
\n" ); document.write( " $\"p=141%2F2\"$
\n" ); document.write( "p=$70.50
\n" ); document.write( "When x=11
\n" ); document.write( " $\"p=-11%2F2%2B75\"$
\n" ); document.write( " $\"p=-11%2F2%2B150%2F2\"$
\n" ); document.write( " $\"p=%28-11%2B150%29%2F2\"$
\n" ); document.write( " $\"p=139%2F2\"$
\n" ); document.write( "p=$69.50 \n" ); document.write( "
