document.write( "Question 1169223: Brenda deposited some money at 6% simple interest in a certificate of deposit. She invested $1500 less than this amount in a mutual fund account bearing simple interest at 11%. If Brenda's total interest income was $1195 for the year, how much did she invest in each account? \n" ); document.write( "

document.write( "ANSWER.  $6500 invested at 11%, and  $6500 + $1500 = $8000 invested at 6%.\r\n" );
