Define a variable and write an inequality to model the given situation.

A law clerk has earned less than $30,000 since being hired. If s is the law clerk's salary, which of the following inequalities models the given situation?
A. s < 30000
B. s >= 30000
C. s <= 30000
D. s > 30000

The answer is C. s <= 30000. This inequality states that the law clerk's salary (s) is less than or equal to $30,000.

The correct inequality to model the situation is:

C. s <= 30000

To define a variable and write an inequality to model the given situation, we can define a variable "s" to represent the law clerk's salary. The law clerk has earned less than $30,000 since being hired, so the inequality representing this situation would be "s < 30000".

Therefore, the correct answer to the question is:
A. s < 30000
