assume that each of the 5 tests is worth 20% of the overall grade:
\n" ); document.write( "---
\n" ); document.write( "0.8*85 + 0.2x = 87
\n" ); document.write( "68 + 0.2x = 87
\n" ); document.write( "0.2x = 87 - 68
\n" ); document.write( "x = (87 - 68)/0.2
\n" ); document.write( "answer:
\n" ); document.write( "x = 95
