2. The prices of different burgers are shown on this sign.

Based on the information from the menu, is the price of a burger a function of the number of patties?

2 patties, no cheese

$4.59

Double Cheeseburger.

2 patties, 2 cheese slices

This is because, the number of patties is the independent variable and the price is the dependent variable. A function can be written as y = f(x), here x is the number of patties. The price of the burger is y. I had this question that is also why I know this is right.

I hope this helps and have a nice day..

There is no direct relationship between the price of the burger and the amount of patties in it.

To determine if the price of a burger is a function of the number of patties, the following calculations must be performed:

First, the price of each hamburger must be divided by the number of patties it has.

Just the patties: $ 4.09, 2 patties and no cheese. 4.09 / 2 = 2.045 per pattie.
Cheeseburger: $ 3.49, 1 patty and 1 cheese slice. 3.49 - 2.045 = 1.445 per cheese slice.
Double Cheeseburger: $ 4.59, 2 patties and 2 cheese slices. In this case, there is a reduction on the price from the cheeseburger, since if the values were the same, this burger should cost $ 6.98.
Big Island: $ 6.79, 4 patties and 4 cheese slices. In this case, the same that for the Double Cheeseburger applies.

Thus, it can be seen that there is no direct relationship between the price of the hamburger and the amount of patties in it.
