The first question is what are the signs: 2 pluses, 2 minuses or one of each which leaves just two answers.
The second question is how do we get 16x^2: is it (8x)(8x) or (4x)(4x)?

Using the Y= on the TI-84, we can compare/contrast the graphs of these two functions.  How does the red compare to the blue?

There are well over 200 boys altogether and only 56 chose Niagara Falls — way less than half so 2 of the answers can be eliminated.
How many boys chose Niagara Falls?
What was the total number of boys?
Use division:
56 out of the total number of boys

This question can be done in many ways.  Students can cross multiply or find a common denominator or even try each of the four answers to find the one that when you add 10  to that number (x + 10) and then divide that by 15, the answer is 4/3.
That’s it — 2 points on the Regents!!
