The population approaches \"+11+\"
\n" ); document.write( "As \"+t+\" increases, \"+.4%5E%281.8t+%29+\"
\n" ); document.write( "approaches zero, so \"+520+%2A+.4%5E%281.8t+%29+\"
\n" ); document.write( "approaches zero
\n" ); document.write( "Suppose \"+t+=+6+%2F+1.8+\"
\n" ); document.write( "\"+.4%5E%28+1.8t+%29+=+.4%5E6+\"
\n" ); document.write( "\"+.4%5E6+=+.004096+\"
\n" ); document.write( "\"+520%2A.004096+=+2.13+\"
\n" ); document.write( "So, \"+B%28t%29+\" is approaching \"+11+\"
\n" ); document.write( "(D) is the answer
\n" ); document.write( " \r
