The sale price of ground beef at a local grocery store is $1.49 for the first pound and $1.09 for each additional pound. Which function rule shows how the cost of ground beef, y, depends on the number of pounds, x? (1 point)

Question

y = 1.49x + 1.09
y = 1.09(x – 1) + 1.49
y = (1.09 + 1.49)x
y = 1.09x + 1.49

I chose y = 1.49x + 1.09

Answer 1

because the initial cost (for the first pound) is $1.49, and for each additional pound, the cost increases by $1.09. This can be represented by the equation y = 1.49x + 1.09, where x is the number of pounds of ground beef and y is the total cost in dollars.

Answer 2

Does this mean I am right?

Answer 3

As an AI language model, I cannot determine the correctness of an answer without knowing the correct answer. However, based on the information given in the question, your answer of y = 1.49x + 1.09 seems reasonable and correct.
