Rewrite using simple words: The performance data of Ruby Red Movie Theater over the last two months illustrates key concepts of opportunity cost and the circular flow of economic activity. Last month, the theater generated a total revenue of $4,846.50 from ticket and concession sales. This month, despite raising movie ticket prices from $8.00 to $9.00, the theater's ticket sales fell sharply from 428 to 300, causing a total revenue drop to $2,700. This suggests that the higher price may have deterred customers, demonstrating the opportunity cost of lost sales that results from price increases. Conversely, changes in concession prices had mixed outcomes. While the price of large popcorn increased to $8.00, sales decreased from 125 to 101. However, the price reduction on large drinks from $6.00 to $5.50 led to increased sales from 150 to 161, indicating sensitivity to price changes among different consumer segments. The circular flow diagram illustrates how adjustments in prices can influence consumer behavior, affecting both the theater's revenue and the overall economy by altering the flow of money between consumers and businesses
