Qusetion: Sarah belongs to a gym and health spa that is conveniently located between her home and her job. It is one of the nicer gyms in town, and Sarah pays $90 a month for membership. Sarah works out three times a week regularly. While she was getting off the treadmill one day, one of the club's personal trainers came by to talk and offered to plan a routine for Sarah that would help her train for an upcoming marathon. The trainer had noticed that Sarah came in regularly, and she commented that most members don't have the self-control to do that. In fact, she explained that there was a study of 8,000 members in Boston area gyms showing that members went to the gym only about five times per month. The study also found that people who choose a pay-per-visit membership spend less money than people who choose a monthly or annual membership fee.

1. At Sarah's club the pay-per-visit fee is $5 per day. Would Sarah save money paying per visit? Assume that a month has 4.3 weeks. What percentage of her monthly $90 fee would she spend if she paid on a per-visit basis?

2. If Sarah goes to the gym three times per week, what percent of days of the year does she use the gym? Round to the nearest percent.
