Applying Coupons and Discounts

The video tutorial explores a word problem involving two coupons at a store, where one offers a 30% discount and the other provides a $100 discount. The teacher defines functions to represent these discounts and examines two options for applying the coupons: subtracting $100 first or applying the 30% discount first. The video also discusses real-world applications, such as gratuity calculations, and introduces the concept of function composition using the coupon example.
