How much is a cup of chopped onion?

It is not possible to give an exact price for a cup of chopped onion, as the price of onions can vary greatly depending on factors such as the time of year, the region, and the grocery store. Additionally, the amount of onion that makes up a cup can vary depending on how finely it is chopped.

As an example, let's consider the average price of a medium-sized yellow onion, which is a common variety used in cooking. At a grocery store in the United States, the average price for a medium-sized yellow onion is approximately $0.50. If we assume that a medium-sized onion yields approximately 1 cup of chopped onion, then the cost per cup would be around $0.50. However, this price can fluctuate based on various factors, and onions may be more or less expensive depending on the specific circumstances.
