Answer:
Option A is correct.
Inequality represents the sale s in dollars:
[tex]0.025s\geq 100[/tex]
[tex]s> 4000[/tex]
Step-by-step explanation:
Let s represents the sales in dollars.
Given :A salesperson at a clothing store earns a commission of 2.5% on all the sales he makes.
Earns a  Commission = 2.5% of s = [tex]\frac{2.5}{100} \times s = \frac{25s}{1000} = 0.025s[/tex]
It is also given that he needs to make to earn a commission of more than $100
then, we have an inequality:
[tex]0.025s\geq 100[/tex]
divide both sides by 0.025 we get;
[tex]s> 4000[/tex]
Therefore, an inequality represents the sales in dollar ; [tex]0.025s\geq 100[/tex] or [tex]s> 4000[/tex]
