June 2008- Math Level 2

<p>i think it was actually $20 per adult.</p>

<p>wait…so can someone tell me what exactly the problem with the adult catering things had in it, and what they wanted</p>

<p>what was this one: 22. Lumber was 222 ft^3</p>

<p>It told you the price was linear, gave you the price for two groups of adults and asked you to find the price for 50 adults. You found out it was modeled by C=20A+50</p>

<p>Remembered 2 more problems, now down to 7 left!</p>

</ol>

<p>it was (if i remember correctly)
20 dollars per adult
50 dollars for initial service</p>

<p>$1550 to cater 75 adults
$1050 to cater 50 adults</p>

<p>how much would it cost to cater 125 adults?</p>

<p>something like that</p>

<p>xeaqs… for the one where it was find the perpendicular line, the slope should actually be positive 3/4, so your equation is off. i remember the original line having -4/3 slope??</p>

<p>What was the one about the f(f(x)) again? i remember the f(f(x)) just not the actual whole problem</p>

<p>It had the graph of -1/2x+4 and asked you to find x such that f(f(x))=3</p>

<p>o i think i do remember getting 4! this is sweet!w

what was 38. on your list haha sorry i have a bad memory :)</p>

<p>It was like the 2nd problem or so it was just like which of these is the least?
A) 6/n
B) 6/(n+1)
C) 6/(n-1)
D) n/6
E) (n-1)/6
or something like that</p>

<p>k thanks .</p>

<p>yeah… ^^^ B</p>

<p>xeaqs8 did u add that to the list?</p>

<p>hey for the 64a^6 one, was that choice e?</p>

<p>ooh we have 46 out of 50!! awesome =]</p>

<p>whoa, on the limit one, since (x-2) on top and bottom cancels, there is no limit</p>
