**Question 101 – “A corporation….”**

OG Explanation is fine.

**Question 102 – “In the coordinate…”**

OG Explanation is fine.

**Question 103 – “If a, b, and c….”**

OG Explanation is fine.

**Question 104 – “If x+y…”**

OG Explanation is fine.

**Question 105 – “On the number line…”**

OG Explanation is okay. It might be easier to pick numbers. Let r=0 and s=4. Since p is halfway between r and s, p=2. Since t is halfway between p and r, t=1. Plugging these numbers in, we get the answer to be 3. The answer is D.

**Question 106 – “If x and y…”**

OG Explanation is fine.

**Question 107 – “If 3/x….”**

OG Explanation is fine.

**Question 108 – “17^3….”**

OG Explanation is fine.

**Question 109 – “Which of the following….”**

OG Explanation is okay. For a number to yield an integer when divided by 10 is the same as saying that the number is divisible by 10.

Choice A: Two odd integers could as 3+7=10

Choice B: 0 and -10 are divisible by 10.

Choice C: 2(5)=10

Choice D: 9+10+11=30

Choice E: an odd integer cannot end in 0. An integer must end in 0 if it is divisible by 10. (It also must be even to be divisible by 0, thus an odd integer is never divisible by 10).

Thus, the answer is E.
