1. Bruce and Doug Ferguson started Ferguson Fitness, providing comprehensive private and corporate fitness programs in Philadelphia, PA. Bruce made a workbook detailing the services they offers. He asks you to help analyze the data to determine how they can increase profits. Switch to the Personal Training worksheet. Create a one-variable data table to calculate the sales, expenses, and profit based on the hours of personal training provided, as follows:
   1. In cell E5, enter a formula without using a function that references cell C4, which is the number of hours of personal training provided.
   2. In cell F5, enter a formula without using a function that references cell C19, which is the total sales from personal training.
   3. In cell G5, enter a formula without using a function that references cell C20, which is the total expenses related to personal training.
   4. In cell H5, enter a formula without using a function that references cell C21, which is the expected gross profit for personal training.
   5. Select the range E5:H10 and then complete the one-variable data table, using cell C4 as the Column input cell.
