Harga Pembelian dan Harga Penjualan | MTs Hasanah Pekanbaru

Introduction

This tutorial covers the concepts of purchasing and selling prices, essential for understanding arithmetic in social contexts, particularly for seventh-grade students. It aims to clarify how these prices are determined and the importance of these calculations in everyday transactions.

Step 1: Understanding Harga Pembelian (Purchase Price)

• Definition: The purchase price refers to the amount paid to acquire a product.
• Calculation:
  1. Identify the cost of the item.
  2. Include any additional costs such as shipping or taxes.
  3. The formula for calculating the total purchase price is:

     Total Purchase Price = Cost of Item + Additional Costs
     

• Practical Tip: Always keep receipts to track your expenses accurately.

Step 2: Understanding Harga Penjualan (Selling Price)

• Definition: The selling price is the amount at which a product is sold to customers.
• Calculation:
  1. Determine the desired profit margin.
  2. Use the purchase price to set the selling price using the formula:

     Selling Price = Purchase Price + Profit Margin
     

• Common Pitfall: Avoid setting the selling price too low, as this may lead to losses.

Step 3: Profit and Loss Calculation

• Understanding Profit:
  • Profit is the difference between the selling price and the purchase price.
  • Formula:

    Profit = Selling Price - Purchase Price
    

• Understanding Loss:
  • Loss occurs when the selling price is lower than the purchase price.
  • Formula:

    Loss = Purchase Price - Selling Price
    

Step 4: Real-World Application

• Example Scenario:
  1. You buy a pair of shoes for $50 (purchase price).
  2. You want to make a profit of $20.
  3. Calculate the selling price:

     Selling Price = $50 + $20 = $70
     

  4. If you sell the shoes for $70, your profit is:

     Profit = $70 - $50 = $20
     

Conclusion

Understanding the concepts of purchase and selling prices is crucial for managing finances effectively. By mastering these calculations, students can apply them in real-life scenarios, ensuring better financial decisions. For further practice, consider calculating the purchase and selling prices for everyday items you buy or sell.
