The rate of bacteria growth in a laboratory experiment was measured at 11% per hour. If this experiment is repeated and begins with 6 grams of bacteria, how much bacteria should be expected after 15 hours? Round to the nearest tenth of a gram.

    Each hour the population rises by a factor of 1.11. So, after 15 hours, you have
    6*1.11^15 = ?
