SET UP A RATIO OF THE 2 INVESTMENTS & INTERESTS:
\n" ); document.write( "45/1,500=X/2,000 CROSS MULTIPLY
\n" ); document.write( "1,500X=45*2,000
\n" ); document.write( "1,500X=90,000
\n" ); document.write( "X=90,000/1,500
\n" ); document.write( "X=$60 WOULD BE THE INTEREST ON THE $2,000 INVESTMENT.
\n" ); document.write( "PROOF:
\n" ); document.write( "45/1,500=60/2,000
\n" ); document.write( "90,000=90,000 \n" ); document.write( "

\n" );
