Final answer:
The student's question pertains to calculating the number of one-topping pizzas sold based on their percentage representation in total monthly sales within a circle graph.
Step-by-step explanation:
The question seems to be examining the concept of percentages within a circle graph to determine the total number of one-topping pizzas sold by 'pizza pie 'n go', given the percentages for the most requested one-topping pizzas. To solve this problem, you would need to take the total number of pizzas sold in a month (1,780) and calculate the number of pizzas per topping by applying the respective percentages. This can involve simple multiplication for each category. For example, if pepperoni pizzas make up 25% of sales, then the number of pepperoni pizzas sold would be 0.25 times 1,780.
Additionally, the question alludes to economic principles such as quantity demanded and price, which may suggest a follow-up question or further analysis on supply and demand, but this is not explicitly required by the initial question provided.
