B: 8(N - 17) = 30
C: 8N - 17N = 30

Answer 1

B: 8(N - 17) = 30

Explanation:

Since the wording multiplies the difference by 8, the appropriate choice is B.

A: "the difference of the product eight times a number and seventeen" It is less ambiguous if you can word it as "the difference of seventeen and the product of 8 and a number is negative 30".

C: "The difference of eight times a number and seventeen times the same number is thirty."
