\n" ); document.write( " The final exam counts as three tests, & a B is received if the final course average is greater than equal to 80
\n" ); document.write( ":
\n" ); document.write( "let f = the score on final test
\n" ); document.write( " $\"%28%2871%2B81%2B85%2B3f%29%29%2F6\"$ => 80
\n" ); document.write( "multiply both sides by 6
\n" ); document.write( "237 + 3f => 6(80)
\n" ); document.write( "3f => 480 - 237
\n" ); document.write( "3f => 243
\n" ); document.write( "f => 243/3
\n" ); document.write( "f => 81 to get at least a B \n" ); document.write( "

\n" );
