Question

The CEO of Mega Sales Enterprises has recently determined that the number of employees he has can be modeled by the equation f(x) = 10x, where x represents the number of years since the company started. If the company has never lost or fired an employee, what does the form of this function tell you about the hiring policy?
Select one:
A. The company hires 10x employees every year.
B. The company hires 10 employees every year.
C. The company hires x employees every 10 years.
D. The company hires 1 employee every 10 years.

Answer 1

Answer:

B. The company hires 10 employees every year.

Step-by-step explanation:

One way to look at this is to look at the units on the number 10. Working strictly with units, we get ...

f(x) = 10x . . . . . . f(x) is employees, x is years

employees = 10·years

Dividing by years, we find the meaning of "10":

employees/year = 10

The division symbol (/) is read as "per", so this means the number 10 in the equation is the number of employees per year that are hired.

10 employees are hired every year.
