The following questions are to be considered independently.

1.	Compute the clubs ROI. (Do not round intermediate calculations. Round your answer to 2 decimal place.)

2.	Assume that the manager of the club is able to increase sales by $80,000 and that as a result operating income increases by $6,000. Further assume that this is possible without any increase in operating assets. What would the clubs ROI be? (Do not round intermediate calculations. Round your answer to 2 decimal place.)

3.	Assume that the manager of the club is able to reduce expenses by $3,200 without any change in sales or operating assets. What would the clubs ROI be? (Do not round intermediate calculations. Round your answer to 2 decimal place.)

4.	Assume that the manager of the club is able to reduce operating assets by $20,000 without any change in sales or operating income. What would the clubs ROI be? (Do not round intermediate calculations.)
