Answer 1

Answer:

Step-by-step explanation:

C. Cost = $19 x u + $9shipping fee

So k = 19u + 9

Answer 2

The function that represent the information is k = 19u + 9

The shipping fee = $9

The company charges $19 per costume.

The shipping fee is acting like a constant in the linear equation while the amount charged for the costumes is dependent on the value u, which is the number of costumes purchased.

k = total cost

number of costumes she orders = u

Therefore, the equation can be represented as follows

k = 19u + 9
