Currently there are three test scores:
\n" ); document.write( "87, 84, 85
\n" ); document.write( "so the current test average is
\n" ); document.write( "(87+84+85)/3 = 85.33333333...
\n" ); document.write( "Now if we assume that the highest grade you can make on the next test is 100
\n" ); document.write( "then the new test average would be
\n" ); document.write( "(87+84+85+100)/4 = 89
\n" ); document.write( "So the answer is no.
\n" ); document.write( "Of course if were possible to score higher that 100 with bonus questions then a score of 104 on the next test would result in a test average of 90.
\n" ); document.write( "and a score of a 102 on the next test would result in a test average of 89.5 which could be rounded to a 90 depending on the specifics of how the instructor records grades.
\n" ); document.write( " \n" ); document.write( "
