The Greens said that since their bill was $21.11, each cheeseburger must cost $2.49 and each
order of medium fries must cost $2.87 each. Are they correct? Justify your answer.

they are not correct

Step-by-step explanation:

To determine if they are correct, we would have to solve the equation from the previous question. Recall;

c represent the cost of a cheeseburger.

f represent the cost of medium fries.

The Browns bought 4 cheeseburgers and 3 medium fries for $16.53. It means that

4c + 3f = 16.53- - - - - - - -1

The Greens bought 5

cheeseburgers and 4 medium fries for $21.11. It means that

5c + 4f = 21.11- - - - - - - -2

Multiplying equation 1 by 5 and equation 2 by 4, it becomes

20c + 15f = 82.65

20c + 16f = 84.44

Subtracting, it becomes

- f = - 1.79

The negative sign cancels out

f = 1.79

Substituting f = 1.79 into equation 1, it becomes

4c + 3 × 1.79 = 16.53

4c + 5.37 = 16.53

4c = 16.53 - 5.37

4c = 11.16

c = 11.16/4

c = $2.79

Each cheeseburger costs $2.79 and each fry costs $1.79

Therefore, they are not correct

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
