**Question 91 – “For a light…”**

**Question 92 – “If b<2…”**

OG Explanation is fine.

**Question 93 – “(-1.5)…”**

OG Explanation is fine

**Question 94 – “Rene…..”**

OG Explanation is fine.

**Question 95 – “In a shipment…”**

OG Explanation is fine.

**Question 96 – “If 8^2x+3…”**

OG Explanation is fine

**Question 97 – “Of the following…”**

OG Explanation is fine.

**Question 98 – “Which of the following…”**

OG Explanation is fine. The easiest way to do this problem is to recognize since x and y are positive, x cannot be divisible by x+y because x cannot be divisible by a number bigger than itself. The same logic applies for y.

**Question 99 – “If a, b,….”**

OG Explanation is fine. Notice that if the numerator is equal to the denominator of a fraction, then that fraction equals 1. So we could rephrase the question: for answer choices A through E, does the numerator equal the denominator?

Choice A: Does a-b=c? No, because a+b=c and b is nonzero.

Choice B: Does a-c=b? No, because a+b=c, which means a – c = – b

Choice C: Does b-c=a? No, b-c = – a

Choice D: Does b-a=c? No, because a+b=c, so b+a=c and a is nonzero.

Choice E: Ford c-b=a? Yes, since a+b=c then a=c-b

The answer is E.

**Question 100 – “Last year Carlos…”**

OG Explanation is fine. Alternatively, we could pick numbers. Supposed he earned $100 last year; then he saved $10. This year he saved 12% of $105. 12% of $105 is $12.60.

$12.60 is a 126% of $10.00. Therefore, the answer is C.
