Composition of Functions Real World Example

The video tutorial explores a word problem involving two coupons at a store: one offering 30% off and the other $100 off. The teacher defines functions to represent these discounts and evaluates the order of applying them to a $500 purchase. The tutorial highlights the importance of order in maximizing savings and relates this to real-world scenarios like restaurant gratuities. Finally, the concept of function composition is introduced, linking it to the problem-solving process.
