You can put this solution on YOUR website!
Your 75% grade accounts of 90% of your final mark.
\n" ); document.write( "Your final exam (I will call it F) accounts for 10%. \r
\n" ); document.write( "\n" ); document.write( "If you want an A (this is 80% or above):
\n" ); document.write( "\"75%2A0.9%2BF%2A0.1%3E=80\"
\n" ); document.write( "Now solve for F
\n" ); document.write( "\"67.5%2BF%2A0.1%3E=80\"
\n" ); document.write( "\"F%2A0.1%3E=80-67.5\"
\n" ); document.write( "\"F%2A0.1%3E=12.5\"
\n" ); document.write( "\"F%3E=12.5%2F0.1\"
\n" ); document.write( "\"F%3E=125\"\r
\n" ); document.write( "\n" ); document.write( "Unfortunately, it is not possible to get above 80 as you would need at least 125 on your final exam. \r
\n" ); document.write( "\n" ); document.write( "Now if you want a B(this is 70% or above):
\n" ); document.write( "\"75%2A0.9%2BF%2A0.1%3E=70\"
\n" ); document.write( "Now solve for F
\n" ); document.write( "\"67.5%2BF%2A0.1%3E=70\"
\n" ); document.write( "\"F%2A0.1%3E=70-67.5\"
\n" ); document.write( "\"F%2A0.1%3E=2.5\"
\n" ); document.write( "\"F%3E=2.5%2F0.1\"
\n" ); document.write( "\"F%3E=25\"\r
\n" ); document.write( "\n" ); document.write( "So this is definately possible! As long as you get over 25%, you will get over 70%. ((Note: this may change if you have rules about passing your final and if different tests are worth different amounts in the 90%, etc.))
\n" ); document.write( "
