The discussion revolves around calculating the percentage discount on a large 14" pizza priced at $11 compared to an 8" pizza priced at $3.99. The area of the pizzas is considered to determine their value. The small pizza's area is proportional to 8², while the large pizza's area is proportional to 14². Based on the area ratio, the large pizza should cost approximately $12.20 if priced according to its size. The discount is calculated as follows: the difference between the expected price ($12.20) and the actual price ($11) results in a discount of about 10%. This calculation confirms that the store's claim of a great deal is accurate, as the discount is approximately 10%.
