<p>I was beyond confused when I saw it, and even more confused when I answered it...</p>
<p>can someone please explain why it's NOT 52? the explanation that collegeboard gave wasn't very helpful...</p>
<p>52+1</p>
<p>subtraction is the difference between the two numbers. customer 149 or 201 was what you omitted. </p>
<p>If you live on a street with a row of houses, or trees whatever. Subtracting is counting the spaces between them.</p>
<p>|<em>|</em>|<em>|</em>|<em>|</em>|</p>
<p>6 spaces, 7 trees. Same idea here.</p>
<p>Correct!</p>
<pre><code>* Here's Why:
The number of customers who were waited on that day is (201 – 149) + 1 = 53, as the total number of customers is those customers numbered 149 to 201 inclusive.

<p>example: customers 4 through 7 waited, so you do 7-4=3, then add +1 because 7 wasnt counted</p>
<p>i just did it,and this kind of thing requires common sense... lol no offense.
LOOK, mini version. numbers 1 thru 9, there's 9 numbers or 8??? numbers 4 to 5, 1 number or 2 numbers?? so u subtract the diff, and add itself as 1 number.</p>
<p>I knew this question because I always calculate the number of pages I have to read for different assignments, based on the page ranges. So if I had to read pgs 169-179, I would have 10 pages to read assuming I had already finished page 169. Otherwise, I'd had 11 pages total. Take out a book and literally count how many pages are in 23-29 or whatever.</p>
