Fitness Fanatics is a regional chain of health clubs. The managers of the clubs, who have authority to make investments as needed, are evaluated based largely on return on investment (ROI). The company's Springfield Club reported the following results for the past year: Sales $ 790,000
Net operating income $ 18,960
Average operating assets $ 100,000
The following questions are to be considered independently.
Required:
1. Compute the Springfield club’s return on investment (ROI)
2. Assume that the manager of the club is able to increase sales by $70,000 and that, as a result, net operating income increases by $18,200. Further assume that this is possible without any increase in operating assets. What would be the club’s return on investment (ROI)?
3. Assume that the manager of the club is able to reduce expenses by $14,000 without any change in sales or operating assets. What would be the club’s return on investment (ROI)?
In addition of finding the ROI for each question, can you help me also to find the Margin and Turnover value for each question from 1-3 also?

Who is better at multi-tasking? in business, employees are often asked to perform a complex task when their atten-tion is divided (i.e., multi-tasking). human factors (may 2014) published a study designed to determine whether video game players are better than non–video game play-ers at multi-tasking. each in a sample of 60 college stu-dents was classified as a video game player or a non-player. participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersec-tion. the simulator was designed to have cars traveling at various high rates of speed in both directions. during the crossing, the students also performed a memory task as a distraction. two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). the researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. “these results,” say the researchers, “suggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task”

Although appealing to more refined tastes, art as a collectible has not always performed so profitably. during 2003, an auction house sold a sculpture at auction for a price of $10,211,500. unfortunately for the previous owner, he had purchased it in 2000 at a price of $12,177,500. what was his annual rate of return on this sculpture?
