The population of a colony of bacteria doubles every 8 hours. If the number of bacteria starts at 80, the population P after t hours is given by P(t)=80*2^t/8. What is an equivalent form of P(t) that shows the approximate hourly growth factor for the bacteria population? A. P(t)=80*1.091^t
B. P(t)=80*1.414^t
C. P(t)=80*1.125^t
D. P(t)=80*1.25^t
