Last year's return on investment (ROI) for the club is:
= 7.2%.
Step-by-step explanation:
a) Data and Calculations:
Sales $12,500,000 
Variable expenses 9,380,000 
Contribution margin 3,220,000 
Fixed expenses 2,716,000 
Net operating income $504,000 
Average operating assets $7,000,000
Return on investment = $504,000/$7,000,000 * 100
= 7.2%
The current investment opportunity this year:
Sales $560,000 
Contribution margin ratio 50% of sales 
Fixed expenses $246,400
Investment cost $750,000
Sales $560,000
Variable costs 280,000 
Contribution margin 280,000 (50% of sales)
Fixed expenses $246,400
Net operating income $33,600
ROI = $33,600/$750,000 * 100 = 4.48%
