Answer: 162.50
Explanation:
The trader's profit can be calculated as follows:
Profit = 30% of 125.00 Dollars
Profit = 0.3 * 125.00 Dollars
Profit = 37.50 Dollars
The trader's selling price would be the sum of his purchase price and profit:
Selling price = Purchase price + Profit
Selling price = 125.00 Dollars + 37.50 Dollars
Selling price = 162.50 Dollars
Therefore, the trader's selling price was 162.50 Dollars.
