A culture of bacteria initially contains 1200 strands. If the rate of increase in the population of bacteria in the culture is directly proportional to the population itself and after 4minutes the population becomes 2000 when accidentally another 500 strands of the same bacteria are added in the culture. Determine the number of strands in the culture after 10 minutes, determine also the growth rate factor before and after the addition of the 500 strands.
