A mold professional uses an antimicrobial chemical in an attic to combat a colony of mold. If the initial number of mold spores
kykrilka [37]

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 costs $5 per hour for a canoe. However, for every rental of one canoe, there is a deposit of $15 regardless.
The expression is then 5x + 15.

This expression will solve how much it costs in total to rent one canoe for x hours.

Gwar [14]

To find the answer, you have to set each one equal to each other.

(160 + 40x = 55x)

Now, you just solve for X.

55x - 40x = 15x

160 / 15 = 15 / 15x

This means 160/15 = x, or is equal to
