Juanita works as a salesperson at an electronic store. She earns a base salary of $400 each week plus a 10% commission on her total sales. Her weekly pay is described by the equation p = 400 + 0.1s, where p is her total weekly pay and s is her weekly sales.

What does (0, 400) represent?
A
The commission earned
B
The base salary
C
The daily sales after a week of sales
D
The total weekly sales

The correct answer is letter B.

Step-by-step explanation:

When we represent a pair like this (0,400) the first number is the "s" of the equation, while the second number is the "p" of the equation. In this case "s" means the total amount Juanita sold in that week and "p" means her income for the week. Since the amount sold is equal to 0, then the total earned is equal to her base salary. So the correct answer is letter B.
