What would be the percent growth or birth rate per individual per hour for the same population mentioned in the previous question (Question 10)?

Options

A. 100
B. 200
C. 50
D. 150

Answer

To find the percent growth or birth rate per individual per hour for the given population, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Initial and Final Population**:
- The initial population (at time t1) is given as 50.
- The population after one hour is given as 150.

2. **Calculate the Increase in Population**:
- The increase in population can be calculated by subtracting the initial population from the final population:
\[ \text{Increase} = \text{Final Population} - \text{Initial Population} = 150 - 50 = 100 \]

3. **Calculate the Birth Rate**:
- The birth rate (or growth rate) can be calculated using the formula:
\[ \text{Birth Rate} = \left( \frac{\text{Number of New Individuals}}{\text{Initial Population}} \right) \times 100 \]
- Here, the number of new individuals is the increase we calculated, which is 100. So we substitute this into the formula:
\[ \text{Birth Rate} = \left( \frac{100}{50} \right) \times 100 \]

4. **Perform the Calculation**:
- Simplifying the fraction:
\[ \frac{100}{50} = 2 \]
- Now multiply by 100:
\[ \text{Birth Rate} = 2 \times 100 = 200\% \]

5. **Conclusion**:
- The percent growth or birth rate per individual per hour for the population is **200%**.
