When the integer k is divided by 7, the remainder is 2. Which of the following expressions below when divided by 7, will have a remainder of 5?
I. 4k + 4
II. 6k + 7
III. 8k + 2  Select:
A) I only	B) II only	C) III only	D) I and II only	E) I, II and III
k = 7j + 2   4k + 4 = 28j + 8 + 4 = 28j + 7 + 5   6k + 7 = 42j + 12 + 7 = 42j + 14 + 5   8k + 2 = 56j + 16 + 2 = 56j + 14 + 4   The answer is I and II only.
