Question 338293: Protozoa are single-celled organisms. Paramecium Aurelia is one type of protozoan. The number of Paramecium Aurelia protozoa doubles every 1.25 days. There was one protozoan on a slide 5 days ago. How many protozoa are on the slide now? How do you write the expression and what is the answer? Thank you!

5 days is 4 doubling periods (5/1.25)

for one protozoan doubling 4 times ___ 1 ___ 2 ___ 4 ___ 8 ___ 16

the expression is ___ N = I [2^(t/d)]
___ N is the current number
___ I is the initial number
___ t is the elapsed time
___ d is the doubling time

N = 1 [2^(5/1.25)] = 16
