The formula to calculate the crime rate is:
\[ CR = \frac{TC}{P} \times 100,000 \]
Where:
A crime rate is defined as the total number of crimes performed per a certain number of people in a specified area. This is typically expressed per 100,000 people.
Let's assume the following values:
Using the formula to calculate the crime rate:
\[ CR = \frac{500}{200000} \times 100,000 = 250 \text{ per 100,000 people} \]
The crime rate is 250 per 100,000 people.
