There are two big problems.
\n" ); document.write( "You really screwed up the first quarter which counts a lot and the final doesn't count much. So it won't help raise your average much.
\n" ); document.write( ".43*50+.43*72+.14*x=65
\n" ); document.write( "To get a 65 average you need 89.5714 on the final
\n" ); document.write( ".14x=4
\n" ); document.write( "x=4/.14
\n" ); document.write( "x=28.57
\n" ); document.write( "To increase by 4 points on the final, you have to improve by 28.57 on the final.
