Refer to the exponential growth model for cholera in Example 2. If we start with 55 bacteria, how many bacteria (to the nearest unit) will be present

(A) In 0.85 hour? 

(B) In 7.25 hours?

Data from Example 2

Cholera, an intestinal disease, is caused by a cholera bacterium that multiplies exponentially. The number of bacteria grows continuously at relative growth rate 1.386, that is,

where N is the number of bacteria present after t hours and N₀ is the number of bacteria present at the start (t = 0). If we start with 25 bacteria, how many bacteria (to the nearest unit) will be present

In 0.6 hour? 

In 3.5 hours?
