Algebra.Com's Answer #79193 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Mr. Jones has $7000 to invest. He invests part at 8% and the rest at 8.5%. The amount at 8.5% makes $65 less at the end of the year than the amount invested at 8%. What amount has he invested in each account? \n" ); document.write( ": \n" ); document.write( "Let x = amt invested at 8% \n" ); document.write( "Then \n" ); document.write( "(7000-x) = amt invested at 8.5% \n" ); document.write( ": \n" ); document.write( "Interest @ 8% = Interest @ 8.5% + $65 \n" ); document.write( ".08x = .085(7000-x) + 65 \n" ); document.write( "; \n" ); document.write( "Find x \n" ); document.write( " |
