Here's how gym membership works for a potential customer: If the customer decides to join the gym, she will pay J on day 0. Then, she can use the gym starting the next day for 5 days (1; 2; 3; 4; 5), paying an additional F on each day she visits. If she goes to the gym on any given day, it costs her (10+ F) that day, but beneÖts her 30 the next day. In other words, her "costs" are a sum of her psychic costs (10) and actual Onancial costs (F). Assume that, when indi§erent, the individual will go to the gym. (a) Suppose the potential customer is a standard exponential discounter with a discount factor of = 12. If gym membership was free (i.e. J = 0 and F = 0) would she join the gym? If so, how many days would she actually go? (b) Suppose the gym did not charge a joining fee. How high could it set the usage fee? What would its revenues from this customer be? (c) Suppose instead the gym decided not to charge a usage fee. How high could it set the joining fee?

Mr. Pascual and Mr. Reyes decide to go to Batangas using a car and a motorcycle, respectively. They agree to meet at UST st so that they will start traveling at the same time. However, at the time of their meet-up, Mr. Reyes is late and he said Mr. Pascual that he will catch up. Mr. Pascual then left UST and start to travel at an average speed of 45.5 kph. After 19 minutes, Mr. Reyes arrived at UST and started to travel to batangas at an average speed of 67.81 kph. What is the total distance traveled in kilometers by Mr. Reyes by the time he catch up with Mr. Pascual? NOTE: The reference point will be at UST
