There are many benefits to timing your practice, including:

(A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. (B) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. (C) BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. (D) EACH statement ALONE is sufficient. (E) Statements (1) and (2) TOGETHER are NOT sufficient.

Correct Answer: D

So I picked A here instead of D because:

(1) Shows T = 6 + s - s = 6 (2) -6^3 = 216 and 6^3 = 216

The explanation for D was given as take the cube root such that you get t = 6

Am I mistaken because the question says t^3 and not (t)^3?

I just don't want to make a stupid mistake on the exam for something as easy as this.

Appreciate any insight

You missed a small part.

-6 ^ 3 will not be 216 infact it will be -216. ( -6 * -6 * -6 ). So only possible value is 6 ^ 3.

Statement 1: s + t = 6 + s Subtract s from both sides to get: t = 6 DONE! Since we can answer the target question with certainty, statement 1 is SUFFICIENT

Statement 2: t³ = 216 Only ONE value of t satisfies this equation. That value is 6 (6³ = 216) So, it must be the case that t = 6 Since we can answer the target question with certainty, statement 2 is SUFFICIENT

Answer: D
