Question 729571: Under Ideal conditions some bacteria can divide and doubles their numbers in less than one-half hour. Supposed one spring day at 6 AM a few such bacteria fall into a can of straw berry syrup in a broken garbage bag behind a snack bar. These conditions warmth, moisture and lots of food are perfect for growth, and the population doubles every 20 minutes. But by the 6 PM bacteria are over crowded and their food is gone. (Let the number of bacteria fell in the can of syrup=x)
How many bacteria were present at the time when the can of syrup was half full?
a.x*(2^35)
b.x*(2^18)
c.x*{(2^36)-1}
d.x*{(2^37)-1}
