To determine the final price of the book after applying the coupon, you start with the original price of the book, which is $15. The coupon provides a discount of $3.

To find the final price, you subtract the discount from the original price:

Final Price = Original Price - Discount

Plugging in the values:

Final Price = $15 - $3 = $12

Thus, the final price after using the coupon is $12. This calculation clearly illustrates how discounts work in everyday transactions, making it relevant for budgeting and financial planning.
