Question

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.

Answer 1

100 +3s≥ 160

You must sell as least 20 items

Explanation:

You make 100 plus 3 dollars per sale

100 +3s

It must be at least 160

100 +3s≥ 160

Now we need to solve to see how many sales

100 +3s≥ 160

Subtract 100 from each side

100-100 +3s≥ 160-100

3s≥ 60

Divide each side by 3

3s/3≥60/3

s≥20

You must sell as least 20 items
