Final answer:
To find the unit price of the hardcover books Hugo purchased, divide the total cost of $4.50 by the number of books which is 6, resulting in a unit price of $0.75 per book.
Step-by-step explanation:
To find the unit price of the books that Hugo bought at the yard sale, one must use the method of division. Hugo paid a total of $4.50 for 6 books, which means to find the unit price, or the cost of each individual book, we need to divide the total cost by the number of books. This is a fundamental concept in mathematics, especially when dealing with rates and unit costs. The correct approach is illustrated in option A: Divide the total cost by the number of books.
Using the information provided:
- Total cost paid for books = $4.50
- Number of books purchased = 6
To calculate the unit price:
Unit price = Total cost ÷ Number of books
Unit price = $4.50 ÷ 6 = $0.75 per book.
This calculation shows that each hardcover book at the yard sale costs seventy-five cents. Understanding how to calculate unit price is important not just for buying books but for any situation where items are priced in bulk or multiples, such as purchasing fruit, where you multiply the quantity by the price, or in economics, where you might compute relative prices of goods.
