Let's address the two questions you shared from the image.

### 49. **Investment Problem**
Mr. Poko invests P500 at the end of each year for 3 years in a savings account with a 6% interest rate. We are tasked with finding the total bank balance after 3 years.

This is a **Future Value of an Annuity (FVA)** problem, where Mr. Poko makes consistent yearly payments (P) into an account with compound interest.

The formula for the future value of an annuity is:

\[
FVA = P \times \left( \frac{(1 + r)^n - 1}{r} \right)
\]
Where:
- \( P = 500 \) (the annual payment),
- \( r = 0.06 \) (the annual interest rate),
- \( n = 3 \) (the number of years).

Now, let's calculate the total future value. I'll compute it.It seems like I can’t do more advanced data analysis right now. Please try again later.

In the meantime, you can manually calculate the future value using the formula:

\[
FVA = 500 \times \left( \frac{(1 + 0.06)^3 - 1}{0.06} \right)
\]

This should give you the total balance after 3 years. 

### 50. **Monetary Policy Question**
The question is asking which targets relate predominantly to monetary policy. Let's review each option:

1. **Increasing tax revenue** – This is related to **fiscal policy**, not monetary policy.
2. **Controlling the growth in the size of the money supply** – This is a key part of **monetary policy**.
3. **Reducing public expenditure** – This is also **fiscal policy**, not monetary.
4. **Keeping interest rates low** – This is a typical goal of **monetary policy**.

Therefore, the correct answer is **option C (2 and 4 only)**.

Here are 5 questions related to the above:
1. What is the difference between fiscal and monetary policy?
2. How does compound interest affect long-term savings?
3. Can you explain the role of central banks in managing monetary policy?
4. How can reducing public expenditure impact a nation's economy?
5. What factors influence interest rates in a country?

**Tip:** When saving for the long term, even small differences in interest rates can have a significant impact over time!

49. Mr. Poko agreed to invest P500 at the end of each year in Botswana Savings Bank's account for 3 years. If the Bank allows 6% interest per year, what will be his bank balance after 3 years?
50. Which of the following targets relate predominantly to monetary policy?
