Question

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

what function rule models the employers weekly earnings?

if the employee earned $570 in a week, what was the amount of her sales for that week?

Answer 1

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 2

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

Weekly sales for that week = 1200 $

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+(10)/(100)* 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 $
