Algebra.Com's Answer #244868 by checkley77(12844)![]() ![]() ![]() You can put this solution on YOUR website! Set up an equation with the unknown amount (x) @ 10% = (58,000-x) amount @ 8%. \n" ); document.write( ".10x=.08(58,000-x) \n" ); document.write( ".10x=4,640-.08x \n" ); document.write( ".10x+.08x=4,640 \n" ); document.write( ".18x=4,640 \n" ); document.write( "x=4,640/.18 \n" ); document.write( "x=25,777.78 amount invested @ 10%. \n" ); document.write( "58,000-25,777.77=32,222.23 amount invested @ 8%. \n" ); document.write( "Proof: \n" ); document.write( ".10*25,777.77=.08*32,222.23 \n" ); document.write( "2,577.77=2,577.77 \n" ); document.write( " |
