What is the primary purpose of the "show calculation" feature in the Food Tool?

The "show calculation" feature in the Food Tool is primarily designed to estimate sales until the next delivery day. This functionality assists in planning and inventory management by allowing users to project sales demand based on existing data. By using this estimation, managers can make informed decisions about how much food to prepare or order, ensuring they meet customer demand while minimizing waste. This predictive capability is crucial in maintaining efficient operations and optimizing inventory levels, which is a key aspect of running a successful restaurant.
