(1 - 0.15)*56 + 0.15x = 70
\n" ); document.write( "0.15x = 70 - (1 - 0.15)*56
\n" ); document.write( "x = ( 70 - (1 - 0.15)*56 )/0.15
\n" ); document.write( "x = 149.333333333
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "you need to get 149.333333333 in the final exam ...
\n" ); document.write( "that's impossible, so you can't get 70% in the class
