In this activity, you will use a quadratic equation or inequality to represent and solve a problem based on real-world situation. Read the scenario, and then answer the questions that follow. You manage a buffet at a local restaurant. You charge $10 for the buffet. On average, 14 customers choose the buffet as their meal every hour. After surveying several customers, you have determined that for every $1 increase in the cost of the buffet, the average number of customers who select the buffet will decrease by 2 per hour. The restaurant owner wants the buffet to maintain a minimum revenue of $120 per hour.

Part A
Would the best representation of this scenario be an equation or an inequality? How do you know?
