You have been hired as a consultant for Peters All In Network $($PAIN$),$ a chain of local gymnasiums. The company has tasked you with determining where to open its next gym site. The company requires a $3$ year payback, and assumes that each gym will either need to be closed or completely overhauled every $4$ years, which makes it essentially a new decision. The company leases its sites, using old JC Penney, Kmarts and Best Buys, so does not worry about the cost and maintenance of the building, simply the gym equipment inside. Calculate the NPV$,$ IRR and Discounted Payback Period for each of the three sites and make your recommendation.
