Answer 3

Which inequality models this problem?

Reiko started a business selling home medical supplies. She spent $6500 to obtain her merchandise, and it costs her $550 per week for general expenses. She earns $900 per week in sales. What is the minimum number of weeks it will take for Reiko to make a profit?


550w > 6500 + 900w
900w > 6500 + 550w
900w < 6500 + 550w
900w ≥ 6500 + 550w
