What is the number grade that I need to get on my final exam to end up with a 72 overall in the class, if I currently have a 86 in the class and the final is worth 30% of my grade.
\n" ); document.write( ":
\n" ); document.write( "We can do it this way,
\n" ); document.write( "Let x = the final exam grade to have 72 average
\n" ); document.write( " $\"%28%287%2886%29+%2B+3x%29%29%2F10\"$ = 72
\n" ); document.write( "multiply both sides by 10
\n" ); document.write( "602 + 3x = 720
\n" ); document.write( "3x = 720 - 602
\n" ); document.write( "3x = 118
\n" ); document.write( "x = $\"118%2F3\"$
\n" ); document.write( "x = 39.3 %, you should be able to handle that, right? \n" ); document.write( "

\n" );
