How much time will the workers spend? Think about the units 🙂
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)?
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?
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!!
