\n" ); document.write( "90*85 + 10f = 100*90
\n" ); document.write( "10f = 100*90 - 90*85
\n" ); document.write( "f = (100*90 - 90*85)/10
\n" ); document.write( "f = 135
\n" ); document.write( "---
\n" ); document.write( "you need 135% on the final, which isn't possible, so you cannot get 90% in the class.
