Test 1- 65
\n" ); document.write( "Test 2- 83
\n" ); document.write( "Test 3- 81
\n" ); document.write( "Test 4- ?
\n" ); document.write( "You're headed into Test 4, the final grade for the semester. Is it possible for you to earn a B grade (85% or better) ?
\n" ); document.write( "-------
\n" ); document.write( "Let the 4th test score be \"x\".
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "(65+83+81+x)/4 = 85
\n" ); document.write( "-----
\n" ); document.write( "(229+x) = 4*85 = 340
\n" ); document.write( "--------------------------
\n" ); document.write( "x = 340-229 = 111
\n" ); document.write( "====
\n" ); document.write( "Looks like you cannot average 85 for the 1st 4 exams.
