Question

A salesperson earns $200 a week plus 4% commission on her sales. Which equation models the relationship between her sales in a given week, x and her weekly earnings, e?

Answer 1

Answer: e = 200 w + 0.04 s

Step-by-step explanation:

Since, the earning in one week = 200 + 4% commission on her sales

Let the sales in w weeks is s,

Then the total amount e he get in w weeks,

e = 200 w + 4 % of s   ( 1 % = 0.01 ⇒ 4 % = 0.04 )

⇒ e = 200 w + 0.04 s

Which is the required relationship between her sales in a given week and her weekly earning.

Answer 2

Earnings = $200 + 4% of Sales
 e = 200 + 0.04*s or e = 200 + 0.04s. Hope this helps!
