44. D Paragraph 5   does    not fit as  a   conclusion, so  eliminate   (A).    This    paragraph   should  come
after the discussion of the tiger moth and its tactics and before the conclusion of the essay.
This indicates the best placement is after the third paragraph, so (D) is the answer.

1. A The    vertex  form    of  a   parabola    is  y   =   a(x –   h)^2    +   k,  where   (h, k)  denotes the vertex. Plug    in
the point (3, –3) into the vertex form to get y = a(x – 3)^2 – 3. The correct answer is (A).

2. C You    can plug    in  to  make    sense   of  this    equation.   Say that    x   =   $100.   The amount  of  the keg
would then be $107 + $17. The $17 must be the untaxed deposit since it is a flat fee rather
than percentage based. Therefore, the tax is $7, which is 7% of the original $100 base
price. The answer is (C).

3. D Whenever   there   are variables   in  the question,   plug    in. Be  sure    to  plug    in  a   number  that    is

divisible   by  3.  Let d   =   300.        of  the original    amount  of  $300    is  $100,   and that    is  deducted

by  the company,    leaving Syed    with    $200.   Then,   subtract    the wire    transfer    fee to  get $200    –

$30 =   $170,   which   is  the target  number. Plug    in  300 for d   in  the answer  choices to  see

which   one is  equal   to  the target  number  of  170.    In  (A),     (300)  –   30  =   70. This    is  not the

target  number, so  eliminate   (A).    Likewise    in  (B),     (300   –   30) =   90, and in  (C),     (300   –

30) =   180.    Neither of  these   is  the target  number, so  eliminate   (B) and (C).    In  (D),     (300)  –

30  =   170,    which   is  the target  number. The correct answer  is  (D).

4. C All    of  the answers are written in  the slope-intercept form    y   =   mx  +   b,  where   b   is  the y-

intercept   and x   and y   are points  on  the line.   Eliminate   (D) because the y-intercept in  that

equation    is  2.  For the remaining   answer  choices,    plug    in  the x-  and y-values    to  determine

which   equation    works.  If  x   =   1   and y   =   6,  (A) becomes 6   =    (1)    +   4.  Solve   both    sides   of

the equation    to  get 6   =   4 . Eliminate   (A).    Choice  (B) becomes 6   =   1   +   4,  so  eliminate   (B).

Choice  (C) becomes 6   =   2(1)    +   4,  or  6   =   6.  Therefore,  the correct answer  is  (C).

5. C Whenever   there   are variables   in  the question    and the answer  choices,    think   Plugging    In. If  2
purchases were made, then p = 2, and the number of bonus points can be calculated as 4(2)
+ 7 = 8 + 7 = 15. If the number of purchases were then increased by 3, the new p equals 5
and the number of bonus points can be calculated as 4(5) + 7 = 27. The bonus points
