If you want to average 77, your total points will need to be:\r
\n" ); document.write( "\n" ); document.write( " $\"77%2A5\"$
\n" ); document.write( " $\"385\"$ \r
\n" ); document.write( "\n" ); document.write( "Averaging 76 on four tests, gives you a running total of \r
\n" ); document.write( "\n" ); document.write( " $\"76%2A4\"$
\n" ); document.write( " $\"304\"$ \r
\n" ); document.write( "\n" ); document.write( "Subtract 304 from 385 to give you the score you'd need.\r
\n" ); document.write( "\n" ); document.write( " $\"385-304\"$
\n" ); document.write( " $\"81\"$ \n" ); document.write( "

\n" );
