Final answer:
To calculate the total revenue for Outdoor Expo in May, one would multiply $300 by the number of individuals for parties smaller than four, and apply a 20% discount for parties of four or more. Unfortunately, the question lacks the number of tours or party sizes in May, preventing the calculation of total revenue.
Step-by-step explanation:
The student's question about the total revenue generated by Outdoor Expo in May based on provided transactions requires a calculation that involves both standard pricing and discount application. With a charge of $300 per person, and considering a 20% discount for parties of four or more, we must apply these pricing rules to each transaction. Unfortunately, the information provided in the question does not include specific transactions for the month of May. Therefore, without the number of tours or the size of each party for the guided fishing tours in May, we cannot calculate the total revenue.
However, it is important to note that for a party of less than four, the revenue per person would be $300. For parties of four or more, a 20% discount is applied, which means each person in such a party would be charged $240 ($300 - 20% of $300).
