**Question 101 – “If the….”**

OG Explanation is fine. Remember if the average of these 4 numbers is 50 then w + x + y + z = 200.

**Question 102 – “[y] denotes…”**

OG Explanation is fine.

**Question 103 – “If x…”**

OG Explanation is fine.

**Question 104 – “If m is a positive…”**

OG Explanation is fine.

**Question 105 – “If t….”**

OG Explanation is fine.

**Question 106 – “If kmn….”**

OG Explanation is fine. The fact that k(m)(n) does not equal 0 is a hint that you might need to multiply or divide k, m, or n.

**Question 107 – “The sequence is…”**

OG Explanation is fine. Listing out the numbers of the sequence and calculating the sum is quite laborious here.

**Question 108 – “A bookstore…”**

OG Explanation is okay.

What is p+h?

Statement 1: 2p+3h=$12.50 INSUFFICIENT

Statement 2: 4p+6h=$25.00 INSUFFICIENT

Statement 2 is just statement 1 multiplied by 2. Graphically, these two equations represent the same lines. Therefore, both explanations together are insufficient. The answer is E.

**Question 109 – “If x, y,…”**

OG Explanation is fine .

**Question 110 – “If n…”**

OG Explanation for 2 is hurried. Since n is both the cube of integer and the square of an integer, it follows that n is also to the 6^{th} power of an integer. (I am actually not sure why this true, I’ll update this explanation later.)
