It would take about 57 hours for the number of spores to be less than 500 spores.

<h3>Exponential Function</h3>

An exponential function is in the form:

y = abˣ

Where y,x are variables, a is the initial value of y and b is the multiplication factor.

Let y is the number of pores after x hours.

a = 6200, b = 100% - 20% = 0.8, hence to be less than 500 spores:

6200(0.8)^\frac{x}{5} < 500

(x/5) * ln(0.8) < ln(0.08)

x > 56.4 hours

It would take about 57 hours for the number of spores to be less than 500 spores.

it would be, 11060 (just from the percent) if you want to know in total add 16590 and 79,000 which would be (95,590 for Landon) and (Elijah would be 90060) in total
