bacteria colonies can increase by 73% every 2 days. if you start with 150 bacteria microorganisms, how large would the colony be
slavikrds [6]

Using an exponential function, it is found that the colony will have 1344 bacteria after 8 days.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

Considering the initial amount of 150, and the growth rate of 73% each 2 days, the equation is given by:

A(t) = 150(1.73)^{\frac{t}{2}}

Hence, after 8 days, the amount of bacteria is given by:

A(8) = 150(1.73)^{\frac{8}{2}} = 1344
