Question

As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be least $100. Write and inequality for the number of sales you need to make and describe the solutions.

Answer 1

50 + 3x ≥ 100

Explanation:

You already know that you are getting $50 that week. Then, for every sale you make $3. Your goal is $100, but you wouldn't complain about making more. Therefore, the inequality sign used here should be the greater than or equal to sign (≥). Your equation should be what is written above, with your payment on the left and earning goal on the right of the inequality sign.
