\n" );
document.write( " Jeremy inherits $200,000 and invests part of the money in bonds with an interest rate of 8%. The remainder of the money is in savings at a 5% rate. What AMOUNT has he invested at EACH RATE if he recieves $14,800 interest for 1 year.?
\n" );
document.write( "So far I have the following:
\n" );
document.write( "let x= dollars invested at 8%
\n" );
document.write( "$200,000-x = dollars invested at 5%.
\n" );
document.write( "Equation as .08x+ .05(200,000-x)=$14,800
\n" );
document.write( "I know you have to clear the decimal and go from there, but when I tried to solve it I got some funky number.
\n" );
document.write( "thank you for your help!

Algebra.Com's Answer #125372 by rajagopalan(174)![]() ![]() You can put this solution on YOUR website! You have solved a major portion: \n" ); document.write( "let x= dollars invested at 8% \n" ); document.write( "$200,000-x = dollars invested at 5%. \n" ); document.write( "Equation as .08x+ .05(200,000-x)=$14,800 \n" ); document.write( "From here 3 more steps.. \n" ); document.write( "1. Expand... \n" ); document.write( "0.08x+10000-0.05x=14800 \n" ); document.write( "2. Simplify \n" ); document.write( "0.03x=14800-10000=4800 \n" ); document.write( "3. Solve \n" ); document.write( "0.03x=4800 \n" ); document.write( "x=4800/0.03=160000 \n" ); document.write( "So ..Answer \n" ); document.write( "dollars invested at 8%=160000 \n" ); document.write( "dollars invested at 5%=40000 \n" ); document.write( "good day \n" ); document.write( " \n" ); document.write( " |
