1) Interest after 1 year = 50000*.09 = 4500
\n" ); document.write( "2nd period 8 months; pro rata \"8%2F12+\" of 9% is 6%
\n" ); document.write( "6% of 54500 is 3270
\n" ); document.write( "Total interest is 7770
\n" ); document.write( "Total 57770\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2) rate for 2 years compounded annually is \"1.2%5E2+=+1.44+\"
\n" ); document.write( "If compounded 6 monthly there are 4 intervals
\n" ); document.write( "6 monthly rate R
\n" ); document.write( "For same Rate \"+1.44+=+%28+1+%2B+R%2F100%29%5E4+\"
\n" ); document.write( "Then \"+1.44%5E0.25+=+1+%2B+R%2F100+\"
\n" ); document.write( "Rearrange \"+R+=+%281.44%5E0.25+-+1%29+%2A+100+\"
\n" ); document.write( "= (1.0954 -1 ) * 100
\n" ); document.write( "= 9.54 % each interval
\n" ); document.write( "Check \"1.0954%5E4+=+1.44\"
\n" ); document.write( "
\n" );
