Final answer:
The question regards the topic of computing the value of an item in mathematics, specifically within the middle school curriculum. It encompasses basic arithmetic operations involving price and quantity to determine total cost, which is an essential life skill.
Step-by-step explanation:
The question provided involves computing the value of an item, which in this instance previously sold for seventy-five cents. Understanding value involves basic arithmetic and concepts of currency, which are commonly taught in mathematics courses at the middle school level. In this context, the value of the item could have implications in terms of price changes over time, potentially involving concepts like inflation or discounts.
For example, to calculate the total cost of purchasing multiple items at a given price, one would multiply the number of items by the price per item. If Coolshirts sells 10 t-shirts at $9 each, the total revenue generated would be 10 t-shirts multiplied by $9 per t-shirt, equaling $90. Similarly, when purchasing fruits, if you buy 10 apples at 50 cents each, you would spend $5.00 in total.
The ability to comprehend and apply these calculations indicates the ability to represent the value of an item and understand the ability for something to be used to purchase something else, which is key in everyday mathematics related to finance and economics.
