The expression in the image appears to be the formula for calculating the monthly payment for a loan (possibly a mortgage), typically referred to as an "annuity" formula. It looks like this:

\[
A = \frac{20000 \cdot \frac{0.14}{12}}{1 - \left(1 + \frac{0.14}{12}\right)^{-12 \cdot 4}}
\]

Here's a breakdown of each part:

- $ 20000 $: This likely represents the loan principal (the amount borrowed).
- $ 0.14 $: The annual interest rate (14% in decimal form).
- $ 12 $: The number of compounding periods per year (monthly compounding).
- $ 4 $: The loan term in years (4 years).
- The denominator represents the factor that reduces the monthly payment based on the interest rate and the number of payments over time.

Let's compute the value of $ A $ (the monthly payment). I'll solve it step by step for clarity.The monthly payment $ A $ is approximately $ 546.53 $.

This is the amount that needs to be paid each month for a loan of \$20,000 over 4 years with a 14% annual interest rate, compounded monthly.

Here are some related questions to explore further:

1. How would the monthly payment change if the loan term was extended to 5 years?
2. What happens to the payment if the interest rate decreases to 10%?
3. How is the formula derived from the general compound interest formula?
4. How would switching from monthly compounding to quarterly compounding affect the payment?
5. What is the total amount paid over the life of the loan?

**Tip:** The longer the loan term, the lower the monthly payment, but the total interest paid will be higher over time.

Calculate the monthly payment for a loan using the formula provided: A = 20000 * (0.14/12) / (1 - (1 + 0.14/12)^(-12 * 4)).
