\n" ); document.write( "Let 3rd exam score be x%.
\n" ); document.write( "Equation:
\n" ); document.write( "(83 + 73 + x)/3 = 83
\n" ); document.write( "156 + x = 249
\n" ); document.write( "x = 93
\n" ); document.write( "---------------
\n" ); document.write( "The student will need 93% on the 3rd exam.
