Final answer:
To calculate the percentage increase from 1970 to 2008 for each type of business organization, use the formula ((ending value - starting value) / starting value) * 100.
Step-by-step explanation:
The question is asking about the percentage increase from 1970 to 2008 for each type of business organization. To calculate the percentage increase, you need the starting value (1970) and the ending value (2008). Let's say the starting value was 100 and the ending value was 150. To calculate the percentage increase, you can use the formula: ((ending value - starting value) / starting value) * 100. Using this formula, the percentage increase would be ((150 - 100) / 100) * 100 = 50%.
Now, this is just an example. You need the actual values for each type of business organization from 1970 to 2008 to calculate the percentage increase. Once you have those values, you can apply the formula to find the percentage increase for each type of business organization.
