Exponential and Logarithmic Models · Exercise 41

Use this scenario: A tumor is injected with $0.5$ grams of Iodine-125, which has a decay rate of $1.15$ per day.

A research student is working with a culture of bacteria that doubles in size every twenty minutes. The initial population count was $1350$ bacteria. Rounding to five decimal places, write an exponential equation representing this situation. To the nearest whole number, what is the population size after $3$ hours?
