The formula to calculate the Return on Investment (ROI) is:
\[ ROI = \left( \frac{R - C}{C} \right) \times 100 \]
Where:
Let's say the revenue generated (R) is $5000 and the cost associated (C) is $2000. Using the formula:
\[ ROI = \left( \frac{5000 - 2000}{2000} \right) \times 100 = 150 \]
So, the Return on Investment (ROI) is 150%.
