Let
\n" ); document.write( "x% of 2500 = 300
\n" ); document.write( " $\"%28x%2F100%29%2A2500=300\"$
\n" ); document.write( " $\"2500x%2F100=300\"$
\n" ); document.write( " $\"cross%282500%29x%2Fcross%28100%29=300\"$
\n" ); document.write( " $\"25x=300\"$
\n" ); document.write( "Divide by 25 both sides of above equation
\n" ); document.write( " $\"25x%2F25=300%2F25\"$
\n" ); document.write( " $\"cross%2825%29x%2Fcross%2825%29=cross%28300%29%2Fcross%2825%29\"$
\n" ); document.write( " $\"x=12\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Rate of return 12% \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
