Daily food budget

What would you consider to be a lower or working class income daily food budget for a family of 4? I’ll explain why I’m asking in the next tweet. And don’t be annoying and get all “clever” by acting like this is impossible to calculate or “it depends.” Looking for a rough range.

Bulk buying and cooking can get my daily cost under $5. So, a family of four could do it for $10-$20. Though, it would be extremely difficult for them, in an urban area, to get their food cost to under $10 a day especially given that food prices have shot up nearly 100% since the start of 2020.

Relevant anecdote: Recently bought an orange to try. Heard it was good. Price? $4! Sadly, it wasn't that amazing.
