<span>The bacteria in a certain culture double every 7.1 hours. The culture has 6,500 bacteria at the start. How much after 4 hrs : Using the formula: A = Ao*2^(t/d) where A = amt after t time
Ao = initial amt (t=0) t = time of action d = doubling time of the bacteria ; A = 6500*2^(4/7.1) A = 6500 * 1.4777 A = 9605 bacteria after 4 hrs</span>
