Question : Sam pays $600 for 30 days of guitar classes. He : 4720

Sam pays $600 for 30 days of guitar classes. He attends an hour-long class every day. If, instead of attending class, he works at a part-time job, he would be paid $5 an hour. Or, he could work at a fast-food outlet and earn $9 per hour. Once he has already paid a nonrefundable fee of $600 to enroll in the class, what is his opportunity cost of attending each hour of class?
