The following questions are to be considered independently.

1. Compute the club's ROI. (Do not round intermediate calculations. Enter your percentage answer rounded to 2 decimal place (i.e., 0.1234 should be entered as 12.34).)

2. Assume that the manager of the club is able to increase sales by $396,900, and, as a result, net operating income increases by $61,600. Further assume that this is possible without any increase in operating assets. What would be the clubs ROI? (Do not round intermediate calculations. Enter your percentage answer rounded to 2 decimal place (i.e., 0.1234 should be entered as 12.34).)

3. Assume that the manager of the club is able to reduce expenses by $45,900 without any change in sales or operating assets. What would be the clubs ROI? (Do not round intermediate calculations. Enter your percentage answer rounded to 2 decimal place (i.e., 0.1234 should be entered as 12.34).)

4. Assume that the manager of the club is able to reduce operating assets by $649,900 without any change in sales or net operating income. What would be the clubs ROI? (Do not round intermediate calculations. Enter your percentage answer rounded to 2 decimal place (i.e., 0.1234 should be entered as 12.34).)
