Question

Piper works in a department store selling clothing. She makes a guaranteed salary of $250 per week, but is paid a commision on top of her base salary equal to 15% of her total sales for the week. How much would Piper make in a week in which she made $2050 in sales? How much would Piper make in a week if she made x dollars in sales?

Answer 1

Hi Bella S

In Slope Intercept Form

y= mx + b

m = slope or rate = 15%

b = 250 her guaranteed salary

y = .15x + 250

According to the info above x = $2050 in sales.

250 + (.15*2050)

Where 250 is salary and (.15*2050) is 15% of her total sales

Hope this helps
