Final answer:
The question lacks the necessary information to calculate the sale price of the soccer ball, such as a discount percentage or a discount amount.
Step-by-step explanation:
The question provided does not give enough information to determine the sale price of the soccer ball. The usual price of a soccer ball is stated as $24.80, but to determine its sale price, we would need to know the discount percentage or the amount by which the price has been reduced during the sale. Without this additional information, we cannot calculate the sale price.
In retail, companies may have sales to encourage consumers to purchase products, often by advertising the products as being significantly differentiated or superior, an example of which is seen in the provided information about the golf ball market. However, this information is not directly relevant to finding the sale price of a soccer ball.
