If w = earnings that week, and s = sales,

w - 450 = s/10, or
10(w - 450) = s, simplified as
10w - 4,500 = s

If the employee made $570 in one week, then w = 570.

10(570) - 4,500 = s, simplified as
5,700 - 4,500 = s, simplified as
1,200 = s.

So the employee made 1,200 sales that week.

Answer:

Weekly earning of employee, E(w) is given by 450+0.1w, where w is the weekly sales.

Weekly sales for that week = 1200 $

Step-by-step explanation:

A phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.

Let w be the  weekly sales, the weekly earning of employee, E(w) is given by

         \(E(w)=450+\frac{10}{100}\times w=450+0.1w\)

So

     Weekly earning of employee, E(w) is given by 450+0.1w, where w is the weekly sales.

Now we need to find what was the amount of her sales for that week, if she earned 570 $

That is

                     570 = 450+0.1w

                     0.1 w = 570 - 450 = 120

                           w = 1200 $

Weekly sales = 1200 $
