Okay, our numbers we have:
\n" ); document.write( "76,74, and 78\r
\n" ); document.write( "\n" ); document.write( "We just need to experiment with numbers.\r
\n" ); document.write( "\n" ); document.write( "We'll say the student got a 92. Let's see their grade.\r
\n" ); document.write( "\n" ); document.write( "76+74+78+92=320
\n" ); document.write( "320/4=80\r
\n" ); document.write( "\n" ); document.write( "So.... The student would need a 92% to get a final grade of \"B\" in the course.
\n" ); document.write( "
\n" );
