Algebra.Com's Answer #535120 by dkppathak(439)![]() ![]() You can put this solution on YOUR website! $6300 is invested, part of it at 10% and part of it at 8%. For a certain year, the total yield is $566.00. How much was invested at each rate? \n" ); document.write( "How much was invested at 10%? \n" ); document.write( "How much was invested at 8%? \n" ); document.write( "solution \n" ); document.write( "let $ X at 10% and Rs $6300-x at 8%\r \n" ); document.write( "\n" ); document.write( "X(10)/100 +(6300-x)8/100 =$566.00 by LCM \n" ); document.write( "10X -8x +50400/100 =566 \n" ); document.write( "10x-8x +50400 = 56600 \n" ); document.write( "2x =56600-50400 = 6200 \n" ); document.write( "x=6200/2 = $3100 \n" ); document.write( "other 6300-3100 = $3200 \n" ); document.write( "answer $3100 at 10% \n" ); document.write( " $3200 at 8% \n" ); document.write( " \n" ); document.write( " |
