I apologize for the incorrect answer earlier. Let me try again.

To convert $8.15 per 500 grams to price per pound, we need to know how many grams are in a pound. There are approximately 453.59 grams in a pound.

So, to find the price per pound, we can use the following calculation:

($8.15 / 500 grams) x (453.59 grams / 1 pound) = $16.98 per pound

Therefore, the price per pound is approximately $16.98.

I hope this answer is correct. Let me know if you have any further questions.
