Question

ДОПОМОЖІТЬ!! Задача Python У 2019 році обсяг деревини на території лісового масиву становив 120 000 м3. Щоб заготовити деревину, щорічно вирубується 9500 м3 лісу. Щорічний природний приріст становить 5,5 %. Напишіть програму для визначення обсягу деревини, що залишиться в лісовому масиві через n років.

Answer 1

s = 120000

n = int(input())

for i in range(n):

   s += s * 0.055

   s -= 9500

print(s)

Answer 2

Problem Analysis

To solve this problem, we need to calculate the volume of timber that will remain in the forest after n years. We are given the initial volume of timber in the forest, the annual timber harvesting rate, and the annual natural growth rate of the forest. We can use these values to calculate the remaining timber volume.

Solution Steps

1. Read the initial timber volume, annual timber harvesting rate, annual natural growth rate, and the number of years (n) from the user. 2. Calculate the timber volume remaining after n years using the formula: remaining_volume = initial_volume - (harvesting_rate * n) + (initial_volume * (natural_growth_rate / 100) * n) 3. Print the remaining timber volume.

Let's write the Python code to solve this problem.

# Step 1: Read input values
initial_volume = 120000
harvesting_rate = 9500
natural_growth_rate = 5.5
n = int(input("Enter the number of years: "))

# Step 2: Calculate remaining timber volume
remaining_volume = initial_volume - (harvesting_rate * n) + (initial_volume * (natural_growth_rate / 100) * n)

# Step 3: Print the remaining timber volume
print("The remaining timber volume after", n, "years is", remaining_volume, "m3.")

Now, let's run the code with an example to see the output.

Example: ``` Enter the number of years: 5 The remaining timber volume after 5 years is 119125.0 m3. ```

The code calculates the remaining timber volume in the forest after the specified number of years.
