Find how many years it takes $1800 to double at 3.2% interest compounded weekly.
\n" ); document.write( "-----------
\n" ); document.write( "Solve:
\n" ); document.write( "3600 = 1800(1+(0.032/52))^(52t)
\n" ); document.write( "--------------
\n" ); document.write( "(1+0.000615)^52t = 2
\n" ); document.write( "---------
\n" ); document.write( "52t = log(2)/log(111.000615)
\n" ); document.write( "52t = 1127.42
\n" ); document.write( "t = 21.68 years
