Task Involving Percentages

To solve a problem involving percentages, you can follow these general steps:

1. Understand the Problem: Read the problem carefully to understand what is being asked and what information is provided.

2. Identify the Variables: Identify the variables involved, such as the original amount, the percentage increase or decrease, and the final amount.

3. Calculate the Result: Use the appropriate formula to calculate the result based on the given information.

4. Example Problem: Let's consider an example where you need to calculate the final price after a discount of 20% on an item that originally costs $50.

- Step 1: Understand the Problem: We need to find the final price after a 20% discount on an item.

- Step 2: Identify the Variables: - Original amount (O) = $50 - Percentage decrease (D) = 20%

- Step 3: Calculate the Result: - The final price (F) can be calculated using the formula: F = O - (O * D/100)

- Substituting the values: F = $50 - ($50 * 20/100) = $50 - $10 = $40

- Step 4: Conclusion: The final price after a 20% discount on the item originally priced at $50 is $40.

This is a basic example of solving a problem involving percentages. Depending on the specific problem, the approach may vary, but these general steps can guide you through the process.
