Exponentials Review U7L6

A group of yeast cells doubles every 4 hours. There is a population of 100 cells.

Write an exponential equation to represent the number of yeast cells Y(t), after t hours. 

Florine-21 has a half-life of 4 seconds. You begin with a 50 mg sample of Florine-21.

Write an exponential equation to represent the amount of Florine-21, f(t), in mg, after t seconds.
