(A) 8n + 2
(B) 8n + 4
(C) 9n + 2
(D) 9n + 3
(E) 9n + 4
Let n =1, implying that one item is purchased for a price of $8 plus $3 shipping -- a total cost of $11.
Since the question stem asks for the total cost of Kim's purchase, the target value is $11.
Now plug n=1 into the answers to see which yields the target value of 11.
Only
C works:
9n + 2 = (9*1) + 2 = 11.
The correct answer is
C.
