Let $\"+r+\"$ = the interest rate
\n" ); document.write( " $\"+120+=+r%2A2000+\"$
\n" ); document.write( " $\"+r+=+120+%2F+2000+\"$
\n" ); document.write( " $\"+r+=+.06+\"$
\n" ); document.write( "--------------------
\n" ); document.write( " $\"+I+=+r%2AP+\"$
\n" ); document.write( " $\"+I+=+.06P+\"$ \n" ); document.write( "
