In the Xiaoshan West Gate vegetable market, a farmer was selling onions, with a total of 100 pounds of onions available. At that time, the market price for onions was $3.00 per pound. An onion dealer told the farmer, "I would like to buy your onions separately, with the onion leaves at $1.50 per pound and the onion whites (the stems) at $1.50 per pound." The farmer, without much thought, sold all the onions. It was only after counting the money that the farmer realized she had sold the onions for less than expected, but by then the onion dealer was nowhere to be found. Using your mathematical knowledge, can you expose the trick of the onion dealer and calculate how much money the farmer actually lost?
