The correct method for calculating the Per Person Average (PPA) is to divide the total revenue by the number of customers who made purchases. In this context, the choice indicating that the calculation involves "people checked in divided by purchased packages" aligns closely with the purpose of determining how much revenue each customer generates on average through their purchases.

This metric is crucial for understanding the success of sales strategies and the popularity of packages among customers. It helps businesses assess the average revenue produced per customer visit, thus providing insights into customer behavior and spending patterns.

Other options, while involving numerical calculations, do not accurately reflect the relationship intended by the PPA. For example, simply dividing revenue by customer visits does not account for whether the customers made purchases, skewing the average and misrepresenting financial performance.
