Find the most important variable in the problem.

If a company hired an additional 12 employees, and every employee needed a phone, it would require 8 more phones. How many phone does the company have available now?

A. The number of phone available

B. The money required to purchase phones

C. The number of employees hired

A

Step-by-step explanation:

Let

x = the number of phone available

If it would require 8 more phones, then the total number of phones will be x + 8.

A company hired an additional 12 employees, and every employee needed a phone, then

x + 8 = 12

x = 4

This means 4 phones were available (and 8 more needed to total in 12 phones for 12 new employees)

Hence, correct option is option A.
