Westkost [7]3 years ago
4 0

Given:

Initial population = 100 algae

Growth rate = 30% per day.

Time = 5 days

To find:

The future amount of population.

Solution:

The exponential growth model is

y=a(1+r)^t

where, a is the initial value, r is the rate of interest in percent and t is time period.

Substituting the given values, we get

y=100(1+\dfrac{30}{100})^5

y=100(1+0.30)^5

Now, solve this.

y=100(1.30)^5

y=100(3.71293)

y=371.293

Therefore, the future value is 371.293 algae.
