How many bananas for $1 dollar?

Excuse me, I'm just wondering, how many bananas would I get for one dollar? I've noticed the prices seem to vary depending on the day and the season, so I'm just trying to get a rough estimate. Could you please tell me, approximately, how many bananas could I expect to purchase with a single dollar? It's just for my personal budgeting, so I don't need an exact figure, but a ballpark estimate would be helpful. Thank you for your time and assistance.
