The buffet restaurant charges $3.25 for the first pound of chicken salad and $2.85 for each pound thereafter. If \( y \) represents the total cost and \( x \) represents the total number of pounds, what is the function rule for this pattern?

A. \( y = 3.25 - 2.85(x - 1) \)

B. \( y = 3.25 - 2.85(x + 1) \)

C. \( y = 3.25 + 2.85(x + 1) \)

D. \( y = 3.25 + 2.85(x - 1) \)

C. Is the answer because when u multiply 2.85 times 1 it'll be 2.85 which is the starting price if added on then the x each time it's extra

The function rule for the total cost of chicken salad is y = 3.25 + 2.85 ( x − 1 ) , where y is the total cost and x is the total number of pounds. This accounts for the first pound's cost and adds the cost of additional pounds. The correct answer choice is D.
