Samantha marsh operates Sam's Spicy Subs & Wraps, a sandwich stand near Jefferson High School. Everyday she sells her special sandwiches and wraps to loyal high school customers who flock to the stand during lunch hour. recently, Sam raised her prices by $1 per sandwich. several customers protested. they said the sandwiches now cost more than buying lunch at the burger shop up the street, or worse yet more than buying lunch at school. Sam explained that her costs had gone up because of new license fees and regulations imposed by the City Health Department. she had no choice but to increase her prices, she said. what are the alternatives, possible costs, and possible benefits of this situation?
