If a book costs $15 and you buy 4, how much do you spend?

• A. $50
• B. $60
• C. $70
• D. $75

Answer: (B)

To determine the total amount spent on the books, you need to multiply the cost of one book by the number of books purchased. In this case, each book costs $15, and you want to buy 4 books. Performing the calculation: Total cost = Price per book × Number of books Total cost = $15 × 4 = $60 Thus, when you purchase 4 books at $15 each, you end up spending a total of $60. This is the correct answer, as it accurately reflects the multiplication of the unit price by the quantity bought.
