The question in the image asks:

"A financial application yields 8.5% per year. By investing R$ 700.00 in this application, what amount will a person have after one year?"

This is a basic interest problem, where we need to calculate the final amount after one year using simple interest. The formula for this is:

\[
A = P \times (1 + r)
\]

Where:
- $ A $ is the amount after one year,
- $ P $ is the principal (initial investment),
- $ r $ is the interest rate.

Given:
- $ P = R\$ 700.00 $,
- $ r = 8.5\% = 0.085 $.

Now, let's calculate:

\[
A = 700 \times (1 + 0.085) = 700 \times 1.085 = 759.50
\]

So, the amount a person will have after one year is **R$ 759.50**.

Would you like more details on how the formula works, or do you have any questions?

Here are five related questions:
1. How would the final amount change if the interest rate was 10% instead of 8.5%?
2. What would be the total after two years with the same interest rate?
3. Can you calculate the interest earned only for the first year?
4. What is the difference between simple interest and compound interest in this scenario?
5. How much would you need to invest to have R$ 1000 after one year at 8.5% interest?

**Tip:** Always express the percentage as a decimal (e.g., 8.5% becomes 0.085) when using it in formulas.
