Question 1069355
If the yeast grows exponentially at the rate of 13.2% per hour, then the amount of yeast y present at the end of h hours is given by:
y=1.132^h
So, to get 500 kg yeast at the end of 8 hours, we must start with:
500=y * 1.132^8
500/1.132^8=y
y=185.4379 kgs of yeast to begin with. ☺☺☺☺
