I would calculate it as
\n" ); document.write( "\"97%2A0.9%2B80%2A0.1=95.3\"
\n" ); document.write( "You multiply the 97 average before the final times its 90% value (0.90 as a decimal),
\n" ); document.write( "multiply the 80 final exam grade times its 10% value (0.10 as a decimal),
\n" ); document.write( "and add them.
\n" ); document.write( "
\n" ); document.write( "For my son, I always calculated the individual value of each assignment in grade points, so he would know how to prioritize different assignments.
\n" ); document.write( "If he had had a 97 average in geometry going into the final, but had pending overdue English work, I would calculate that the geometry final could get him from
\n" ); document.write( "\"97%2A0.9%2B0%2A0.1=87.3\" to \"97%2A0.9%2B100%2A0.1=97.3\",
\n" ); document.write( "so the pending English work that his passing depended on was a much higher priority that the geometry final that could at most make the difference between a B and an A.
\n" ); document.write( "In the same way, at any time during the school year, completing some assignment that got him 1 or 2 points in the final grade could be shrugged, as long as he did not do that too often.
