Q1) The growth rate of a certain strain of bacteria is unknown, but assumed to be proportional to the current size. When an experiment started, it was estimated that there were about 1500 bacteria, and an hour later there were 2000. How many bacteria would you predict there are 4 h after the experiment started?
