Simple interest means that the investor earns the same % of the
\n" ); document.write( "principal each year. The principal is $6000.
\n" ); document.write( "So, for 1 year he earns interest = \"+6000r+\" where \"+r+\" is the rate of interest.
\n" ); document.write( "You are given that he earned $270 in interest after 2 yrs
\n" ); document.write( "\"+270%2F2+=+135+\" was earned in each of those 2 yrs.
\n" ); document.write( "---------------
\n" ); document.write( "Let \"+I+\" = interest earned in a year.
\n" ); document.write( "\"+I+=+6000r+\"
\n" ); document.write( "\"+r+=+I+%2F+6000+\"
\n" ); document.write( "\"+r+=+135+%2F+6000+\"
\n" ); document.write( "\"+r+=+.0225+\"
\n" ); document.write( "\"+.0225%2A100+=+2.25+\"
\n" ); document.write( "The simple interest rate was 2.25%
\n" ); document.write( "
