Dina bought a ticket to a concert at IDR 500.000. She sold her ticket for IDR 525.000. How many percent was her profit?

1. Break Down the Problem

To find the profit percentage, we first need to determine the profit made by Dina. Profit can be calculated by subtracting the cost price from the selling price. After finding the profit, we can calculate the profit percentage using the following formula:

$\text{Profit Percentage} = \left( \frac{\text{Profit}}{\text{Cost Price}} \right) \times 100$

2. Relevant Concepts

• Cost Price (CP) = IDR 500,000
• Selling Price (SP) = IDR 525,000
• Profit = SP - CP

3. Analysis and Detail

1. Calculate the profit: $\text{Profit} = \text{Selling Price} - \text{Cost Price} = 525,000 - 500,000 = 25,000$

2. Calculate the profit percentage: $\text{Profit Percentage} = \left( \frac{25,000}{500,000} \right) \times 100 = 5\%$

4. Verify and Summarize

The calculations indicate that Dina's profit from selling the concert ticket is IDR 25,000, which corresponds to a profit percentage of 5%.

Final Answer

Dina's profit percentage is 5%.
