Algebra.Com's Answer #484719 by solver91311(24713) You can put this solution on YOUR website! \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Your answers are whack because the problem makes no sense. Even if the amount invested at 30% was zero and all of the $20,000 was invested at 25%, you would be getting $5000. So either your interest rates are out to lunch or the total amount of interest is missing a zero. I highly suspect the latter.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "John \n" ); document.write( " \n" ); document.write( "Egw to Beta kai to Sigma \n" ); document.write( "My calculator said it, I believe it, that settles it \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
