I'm stuck. Please show formulas used.

Create a workbook to determine which gym to join. Assume that you have narrowed it down to five different gyms and the only difference between them is the price you will have to pay. Assume that you like the facilities at each gym. The worksheet should be flexible enough so that the person using the worksheet can enter input parameters that will change the calculations. The input parameters are: the number of visits to the gym each month, the number of months' membership, the number of personal training hours per month, the number of massage sessions per visit, and the state in which the membership will primarily be used. The calculations on the worksheet should change based on changes in the input parameters. Each gym that you are considering differs based on: the sign-up fee, the monthly charge, the discounted hourly charge for personal training, the half-hourly charge for massage sessions, and the per visit charge You only have to pay the sign-up fee once; it is a non-recurring fee. The rest of the fees are based on use or time. Gyms charging monthly fees charge that fee whether or not you use the gym. Gyms charging per visit fees only charge that fee when you use the gym. One of the gyms, Phenomenal Fitness, charges a small monthly charge and a per visit charge. The fee information has been summarized into a table already to help make it easier to understand the fee structures for the different gyms.
