You can put this solution on YOUR website!
4000 = 2,000*e^(0.08)*t
\n" ); document.write( "4,000/2,000 = e^0.08t
\n" ); document.write( "2 = e^0.05t
\n" ); document.write( ":
\n" ); document.write( "Find the natural log of both sides
\n" ); document.write( "ln(2) = ln(e^(.08*t))
\n" ); document.write( ":
\n" ); document.write( "use the log equiv of exponents
\n" ); document.write( "ln(2) = .08t*ln(e)
\n" ); document.write( ":
\n" ); document.write( "The nat log of e is one, so we just have
\n" ); document.write( ".693 = .08t
\n" ); document.write( "t = \".693%2F.08\"
\n" ); document.write( "t = 8.66
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution on a calc: enter 2000*e^(.08*8.66) = 3993 ~ 4000 \n" ); document.write( "
\n" );
