assume an A is for the range 90% to 100% inclusive:
\n" ); document.write( "---
\n" ); document.write( "(1 - 0.10)*91 + 0.10x = 1.00*90
\n" ); document.write( "(0.90)*91 + 0.10x = 90
\n" ); document.write( "0.10x = 90 - (0.90)*91
\n" ); document.write( "x = (90 - (0.90)*91)/0.10
\n" ); document.write( "x = 81
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "you need 81 or higher on the final
