Final Answer:
No, the price of a burger is not solely a function of the number of patties; it also depends on additional factors like the presence of cheese.
Step-by-step explanation:
The menu presents different burger options with varying prices, indicating that the cost depends on factors beyond just the number of patties. For example, the Cheeseburger, priced at $3.49, has a different cost than the Just the Patties option, which consists of 2 patties but is priced at $4.09.
This discrepancy suggests that additional components, such as cheese, contribute to the overall price. Similarly, the Double Cheeseburger, with a price of $4.59, shows that the inclusion of extra cheese impacts the cost. The Island burger, priced at $6.79, features 4 patties and 4 cheese slices, reinforcing that the composition of the burger, including both patties and cheese, influences the price.
Therefore, the price of a burger is a multifaceted function, considering both the number of patties and other ingredients like cheese in determining its overall cost.
