Which operational reason explains why a food bank might spend only a portion of received funds on purchasing food even when they solicit cash donations?

Food banks never use cash for administrative costs because federal law mandates that 100% of donated cash be converted to canned goods only.

Food banks typically transfer all cash donations to unrelated municipal projects; they do not purchase food or cover distribution costs.

Cash donations are always hoarded because food banks prefer to accept in-kind canned goods when they want to supply fresh produce to clients.

Funds are used for logistics (transportation, refrigeration, staff/volunteer coordination), storage, and purchasing items that meet client needs—so not all donated cash goes directly to food purchases but supports the distribution system.
