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)

D. y = 3.25 + 2.85(x – 1)

Step-by-step explanation:

The amount charged by the restaurant after the first pound of chicken is discounted when compared with the amount charges for the first found.

Given that the buffet restaurant charges $3.25 for the first pound of chicken salad and $2.85 for each pound thereafter and y represents the total cost and x represents the total number of pounds.

Then;

For the first pound,the fee paid is $3.25

The subsequent pounds will be x -1 hence the cost will be $2.85(x -1)

Hence the total cost y = 3.25 + 2.85(x - 1)

i think the correct option is the second option.
