What is an Equation?

An equation is a mathematical statement formed when two expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

Ashleigh hires a group of security staff.

The average of the time a security staff works is 80 hours / month.

The remuneration for the work is $14/ hour.

The total monthly labor cost is $23,520

Let she hired n number of security staff .

The equation to determine the number of security staff hired is,

If n number of people are hired then,

The remuneration for 1 security staff is 80 * $14

The remuneration for n security staff is 80 *$14 *n

This will be equal to $23520

23520 = 80 * 14 * n

On solving this,

n = 23520 / ( 80 *14)

n = 21

Therefore, the number of security staff recruited is 21.
