The text in the image is in the Khmer language. It translates to:

"A person deposited 2500 dollars in a bank that offers an annual interest rate of 10%. How many years will it take for the deposit to double?"

Let's solve this problem!

To find out how many years it will take for the deposit to double, we can use the formula for compound interest. However, since the problem asks for the deposit to double, we can also use the **Rule of 72** for a quick estimate:

\[
\text{Number of Years} = \frac{72}{\text{Interest Rate}}
\]

Given:
- Interest rate = 10%

\[
\text{Number of Years} \approx \frac{72}{10} = 7.2 \text{ years}
\]

So, it will take approximately 7.2 years for the deposit to double with an annual interest rate of 10%.

Here are 5 related questions you might find interesting:
1. What is the formula for compound interest, and how can it be applied here?
2. What is the "Rule of 72," and why does it work for estimating doubling time?
3. How does the time to double change with different interest rates?
4. What if the interest was compounded monthly instead of annually?
5. How would inflation affect the real value of the doubled deposit?

**Tip:** The Rule of 72 is a quick way to estimate the time needed to double an investment at a fixed annual interest rate.

A person deposited 2500 dollars in a bank that offers an annual interest rate of 10%. How many years will it take for the deposit to double?

Learn how to calculate the time needed to double a $2500 deposit at a 10% annual interest rate using the Rule of 72. This simple rule gives an estimate of the doubling time in finance, ideal for high school students and financial beginners.
