The count in a bacteria culture was 200 after 15 minutes and 1200 after 35 minutes. Assuming the count grows exponentially,

What was the initial size of the culture?   


Find the doubling period.   


Find the population after 80 minutes.   


When will the population reach 13000

Didn't you submit similar problem with different values earlier (answered by two experts)?

hear here; can use P(t)=P*b^t, or can use P(t)=P*e^(kt)

Try using the ordered pairs (0,200) and (20,1200) to take the place of (15,200) and (35,1200). Then with the equation that results from that, you can use x = -15 to find the initial value. the exponential equation y = ab^x can also be used.
