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.
