To effectively determine the price per serving of food items, what must you do?

To determine the price per serving of food items, it is essential to divide the total cost by the number of servings. This method allows for a precise calculation of what each individual serving costs. By taking the total expenditure for a food item and spreading it across all servings, you arrive at a clear price per serving, making budgeting and meal planning more manageable.

For instance, if a dish costs $20 to prepare and yields 4 servings, dividing $20 by 4 gives a price of $5 per serving. This ensures that you can accurately assess how much you are spending per serving, which is crucial for effective meal planning and cost management.

Other methods mentioned, like multiplying total costs or adding costs and servings, do not yield the price per serving, and estimating based on size lacks the precision needed for financial planning. Therefore, dividing total cost by the number of servings is the correct and most efficient approach to accurately calculate the cost per serving.
