Question

the population of bacteria in an experiment increases by 84% every 2 days. if there were 75 bacteria microorganisms at the beginning, how many would there be after 20 days? future amount = ? (1 + )^ future amount = i(1 + r)^t enter the number that belongs in the green box.

Explanation:

Step1: Identify the initial amount

The initial number of bacteria $I$ is 75, which goes in the green - box.

Step2: Identify the growth rate

The growth rate $r$ is 84% or 0.84.

Step3: Calculate the number of 2 - day periods

The time period is 20 days. Since the growth occurs every 2 days, the number of 2 - day periods $t=\frac{20}{2}=10$.

Answer:

75
