Set f = number of females
\n" ); document.write( " m = number of males
\n" ); document.write( "f = m + 48
\n" ); document.write( " $\"13%2F5+=+f%2Fm\"$
\n" ); document.write( " $\"13%2F5+=+%28m+%2B+48%29%2Fm\"$
\n" ); document.write( "do cross products
\n" ); document.write( " $\"13m+=+5m+%2B+240\"$
\n" ); document.write( "add -5m to each side
\n" ); document.write( "8m = 240
\n" ); document.write( "divide each side by 8
\n" ); document.write( " m = 30
\n" ); document.write( "Since f = m + 48, f = 30 + 48 = 78
\n" ); document.write( "The total number of teachers is m + f = 30 + 78 = 108 \n" ); document.write( "

\n" );
