Depends on what percentage that test is as part of the entire grade.
\n" ); document.write( "Assume it's X percent.
\n" ); document.write( "Then,
\n" ); document.write( "\"G=84%281-X%29%2B75%2AX\"
\n" ); document.write( "So if it's 10% of your grade,
\n" ); document.write( "\"G=84%281-10%2F100%29%2B75%2810%2F100%29\"
\n" ); document.write( "\"G=75.6%2B7.5\"
\n" ); document.write( "\"G=83.1\"
\n" ); document.write( "
\n" );
