Algebra.Com's Answer #76641 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let x = the amount invested at 3.5%, then ($25000-x) = the amount invested at 4%. \n" ); document.write( "The dividend earned on the first amount is 3.5% of x and this can be written as: 0.035x. \n" ); document.write( "The dividend earned on the second amount is 4% of ($25000-x) and this can be written as 0.04($25000-x) \n" ); document.write( "The sum of these two dividend amounts is given as $900 \n" ); document.write( "We have enough now to write the necessary equation to solve for x. \n" ); document.write( "0.035x + 0.04(25000-x) = 900 Simplify and solve for x. \n" ); document.write( "0.035x+1000-0.04x = 900 Combine like-terms. \n" ); document.write( "-0.005x+1000 = 900 Subtract 1000 from both sides. \n" ); document.write( "-0.005x = -100 Divide both sides by -0.005 \n" ); document.write( "x = 20,000 \n" ); document.write( "$20,000 was invested at 3.5% \n" ); document.write( "$5,000 was invested at 4% \n" ); document.write( "Check: \n" ); document.write( "$20,000(0.035)+$5,000(0.04) = $700+$200 = $900 Total dividends earned. \n" ); document.write( " \n" ); document.write( " |
