Answer:
A) 
B) $1200
Step-by-step explanation:
Let w represent employee's weekly sales and 
be total weekly earnings.
We have been given that a phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.
A) The total weekly earnings of employee would be weekly salary plus 10% of weekly sales.
10% of weekly sales, w, would be 
Therefore, the function models the employee's weekly earnings.
B) To find the weekly sales in the week, when employee earned $570, we will substitute 
in our formula and solve for w as:
Therefore, the amount of employee's weekly sales was $1200.
The situation can be modeled with the linear equation:
$75 + y*($75/x) = $100
<h3>
Which of the following equations represents this situation? </h3>
We know that if she wors for x hours, she earns $75.
This means that the amount that she gets per hour is:
R = $75/x.
Now, if she works y more hours, then she gets another $25 (for a total of $100).
We can write this as a linear equation:
y*($75/x) = $25
We can rewrite this as:
$75 + y*($75/x) = $100
So the correct option is B.
