Question

Anna works in a department store selling clothing. She makes a guaranteed salary of $350 per week, but is paid a commision on top of her base salary equal to 25% of her total sales for the week. How much would Anna make in a week in which she made $1100 in sales? How much would Anna make in a week if she made x dollars in sales?

Answer 1

$625

350+

1) Gathering the data:

Anna's Salary: $350 weekly + 25% of her total sales

2) Let's write Anna's earnings as an equation:

E= 350 +0.25s Anna's earning per week

Now we can answer this question:

"How much would Anna make in a week in which she made $1100 in sales?"

Plug into that the total sales (1100):

E= 350 +0.25s

E= 350 +0.25(1100)

E= 350 +0.25s

E =$625

"How much would Anna make in a week if she made x dollars in sales?​"

Anna then would make her $350 +0.25x
