The doubling period of a bacteria population is 10 minutes. At time t = 110 minutes, the bacterial population was 800.
goldenfox [79]

The initial population at time t = 0 was 0.39 while the size of the bacteria population after 4 hours was 6553600

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let y represent the bacteria population at time t. a represent the initial population at t = 0. Since the doubling period of a bacteria population is 10 minutes, hence:

y=a(2)^\frac{t}{10}

At time t = 110 minutes, the bacterial population was 800. Hence:

800=a(2)^\frac{110}{10} \\\\a = 0.39

At 4 hours (240 minutes):

y=0.39(2)^\frac{240}{10} =6553600

The initial population at time t = 0 was 0.39 while the size of the bacteria population after 4 hours was 6553600
