22. A. To find the average, add the two quantities
and divide by 2:
3y + 1.
*Use TACTIC 6. Let y = 1. Then 4y + 3 = 7
and 2y 1 = 1. The average of 7 and 1 is
= 4. Of the five choices, only 3y + 1 is
equal to 4 when y = 1.
23. D. Judy intends to go to the
each month in 2007 except in July and August,
when she plans to go 3 times each month. A single
admission costs $3.50, a pass valid for unlimited
visits in any 3-month period can be purchased for
$18, and an annual pass costs $60.00. What is the

than 3; to distinguish it from choices D and E,
test 5: 52 + 2(5) 6 = 29, which is greater than
52 2(5) + 6 = 21. Eliminate A, B, and D. Now,
to distinguish between C and E, use your calculator
to test a number between 3 and 4, say 3.5.
It works (13.25 >
17. A. Use TACTIC 6: replace variables with numbers.
If 2 widgets cost 10 cents, then widgets
cost 5 cents each; and for 3 dollars, you can
get 60 widgets. Which of the choices equals
60 when w = 2, c = 10, and d = 3?
Only .
*Convert d dollars to 100d cen
Also, since choice D is about 94, which is
much more than half the area of the square, it
is much too large. Guess between C (about
43) and E (about 50). If you remember that
the way to find shaded areas is to subtract,
guess C: 144 32 .
*The area of the
90 right triangle,
OD is 2 (one-half
of OA). Then,
DE = 4 2 = 2.
7. C. Use TACTIC 10: dont do more than you have
to. In particular, dont solve for x. Here
5x + 13 = 31
5x = 18
5x + 31 =
18 + 31 = 49
= =7.
8. C. This is a relatively simple ratio, but us
prime. Try C: 17 is prime, and is a factor of
255: 255 17 = 15.
*255 = 5 51 = 5 3 17.
15. D. Using your calculator, test the choices, starting
with E (since you want the largest value):
112 + 8(11) 3 = 121 + 88 3 = 206,
and
112 + 7(11) + 8 = 121 + 77 + 8

3. C. As in question 2, if you get stuck trying to
answer this, use TACTIC 2: look at the
diagram.
Square OPQR, whose area is 8, takes up most
of the quarter circle, so the area of the quarter
circle is certainly between 1

in this chapter.
1. E. Use TACTIC 1: draw a diagram representing a
pile of books or a bookshelf.
In the 2 years the number of French books
Diana read was 7 + 2x, and the total number of
books was
a = 100?
A and B: = 1.
Eliminate C, D, and E; and test A and B with
another value, 50, for a:
50 (50% of 50) = 50 (25) = 2.
Now, only works: = 2.
26. A. Set up a ratio:

Then there are 120 = 80 men and

Russians, there are 120 72 = 48 Americans,
of whom 30 are men, so the other 18 are
women.
Finally, the fraction of American women is

an integer x such that x3 = 272 = 729? Use

Try choice D: 16. Is there an integer x such
that x3
*Since Karen has at least 41 books, Jessica
has at least 205. But Jessicas total must be a
multiple of 4 and 5, hence of 20. The smallest
multiple of 20 greater than 205 is 220.

Judy is now 20, Adam is 1
