The doubling time of a type of bacteria is 35 minutes. If every bacterium reproduces, then after 35 minutes a population of 64 bacteria will have grown approximately to what size?

If the doubling time is 35 mins, and the question is what is the population of 64 bacteria after 35 mins, if everyone of them reproduce. Then it would be double the 64. which equals 128.
