Noah manages a buffet at a local restaurant. He charges $10 for the buffet. On average, 16 customers choose the buffet as their meal every hour. After surveying several customers, Noah
has 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 $130 per hour.
Noah wants to model this situation with an inequality and use the model to help him make the
best pricing decisions.
