A jewelry sales person earns a base salary of $200 a week plus 25% of all of her sales over $300.

This situation could be represented by the expression:

200 +.25 (x - 300)

Which of the following describes the meaning of the variable X for this situation?

A. The total amount of sales after the first $300

B. The total amount of salary earned.

C. The amount of commission earned.

D. The total amount of sales

D. The total amount of sales

Step-by-step explanation:

We have been given that a jewelry sales person earns a base salary of $200 a week plus 25% of all of her sales over $300.

This situation has been represented using the expression 200 +.25 (x - 300)

Here 200 is the base salary. 0.25 corresponds to 25%. The factor (x-300) corresponds to the amount of sales over 300 dollars. This implies that x represents the total sales.

Therefore, x represents the total amount of sales. Hence, option (D) is the correct answer.
