Yes, this sentence can be translated in many ways that weren't considered.

Directly, it means "How many/much" (The question word for amounts/numbers) "the price" "my" "food". So a lot of translations fit perfectly, including yours.

I agree

Agree. This English sentence is unclear. Are you wanting to know how much food you have? Or...how much your food costs?

That would mean 'how much/many a lot,' doesn't make much sense.

yeah that happened to me as welllllll
