The question provided is asking about the expenditure of a company for monitoring air pollution, which was Rp. 150,000 in 1995. The expenditure is assumed to increase by 6% per year. The problem is to calculate:

1. The company's annual expenditure in the year 2000.
2. The total expenditure from 1995 to 2000.

### Step 1: Calculating the expenditure in the year 2000
The expenditure increases by 6% per year. This follows the formula for compound interest:

\[
P_t = P_0 \times (1 + r)^t
\]

Where:
- \( P_t \) is the expenditure in year \( t \),
- \( P_0 = 150,000 \) is the initial expenditure in 1995,
- \( r = 6\% = 0.06 \) is the rate of increase per year,
- \( t = 5 \) years (since 2000 is 5 years after 1995).

### Step 2: Calculating the total expenditure from 1995 to 2000
The total expenditure over several years is the sum of all the annual expenditures from 1995 to 2000. This is the sum of a geometric series:

\[
\text{Total Expenditure} = P_0 \times \left( 1 + (1 + r) + (1 + r)^2 + \cdots + (1 + r)^t \right)
\]

Let me calculate both parts.1. The company's annual expenditure in the year 2000 is approximately **Rp. 200,734**.
2. The total expenditure from 1995 to 2000 is approximately **Rp. 1,046,298**.

Would you like more details or have any questions?

Here are 5 related questions you might consider:
1. How would the total expenditure change if the growth rate was 8% instead of 6%?
2. What would the expenditure be in 2005 if the same 6% annual increase continues?
3. How does compound growth affect long-term financial planning for businesses?
4. Can the expenditure be modeled using continuous growth instead of yearly increments?
5. How does inflation impact such calculations in real-world scenarios?

**Tip**: Compound growth magnifies over time. Understanding how it works is crucial for long-term financial planning.

Pengeluaran dari suatu perusahaan untuk mengawasi polusi udara adalah Rp. 150.000 di tahun 1995. Dengan asumsi bahwa pengeluaran meningkat 6% per tahun. Berapa pengeluaran tahunan perusahaan tersebut pada tahun 2000? Berapa total yang dikeluarkan dari tahun 1995 sampai tahun 2000?

Calculate the annual expenditure of a company starting at Rp. 150,000 in 1995, assuming a 6% annual increase. This problem explores compound growth and geometric series, offering a detailed solution to determine expenditure in 2000 and the total amount from 1995 to 2000.
