As a salesperson, you are paid $100 per week plus $3 per sale. this week you want your pay to be at least $160. write an inequality for the number of sales you need to make, and describe the solutions.

First, you would need to create an equation for this problem. Let x represent the number of sales made. 
$100 + $3x = $160

Next, you would need to isolate the x. 

Subtract $100 from both sides. 
$3x = $60

Now, all you would need to do is divide both sides by $3. 
x = 20

You would need to make at least 20 sales. 

I hope this helps!
