Final answer:
The formula for calculating the increased value of a business due to community labor is provided, along with an example.
Step-by-step explanation:
The formula for determining the increased value of a business primarily due to community labor is:
Value of business at beginning + Fair rate of return (10 percent) = SP - Rest is CP
For example, if the value of a business at the beginning is $1,000,000 and the fair rate of return is 10 percent, the SP (Selling Price) would be $1,100,000. The rest, which is the CP (Community Labor), would be $100,000.
