A sample of bacteria is decaying according to a half-life model. If the sample begins with 500 bacteria, and after 17 minutes there are 250 bacteria, after how many minutes will there be 40 bacteria remaining? When solving this problem, round the value of k to four decimal places and round your final answer to the nearest whole number.
