a 1000 acres of forest decreases at an annual rate of 22%, write a function
To write a function that calculates the remaining acreage of a forest over time, given an initial acreage and an annual rate of decrease, you can use the following steps:
1. Define a function called `calculate_remaining_acreage` that takes two parameters: `initial_acreage` (the initial acreage of the forest) and `annual_rate` (the annual rate of decrease).
2. Inside the function, calculate the remaining acreage by multiplying the initial acreage by (100 - annual_rate)%, since the annual rate is given as a percentage decrease.
3. Return the remaining acreage.
Here's the function written in Python:
```python
def calculate_remaining_acreage(initial_acreage, annual_rate):
remaining_acreage = initial_acreage * (100 - annual_rate) / 100
return remaining_acreage
```
You can then call this function with the initial acreage of the forest (e.g., 1000 acres) and the annual rate of decrease (e.g., 22%) to get the remaining acreage:
```python
initial_acreage = 1000
annual_rate = 22
remaining_acreage = calculate_remaining_acreage(initial_acreage, annual_rate)
print(remaining_acreage)
```
The output will be the remaining acreage of the forest after the specified annual decrease rate is applied. In this case, it will be 780 acres.
