Answers and Complete Explanations for Practice Test 2
21. C. In each pint, if 1 part out of the 4 parts is vinegar, then 1 ⁄4 of the pint is vinegar. Thus, in
each pint, if 1 part out of the 4 parts is vinegar, then 1 ⁄4 of the pint is vinegar. Thus, 1 ⁄4 # 16
tells the number of ounces of vinegar in each pint. Then multiply that by the number of
pints (3). Thus, the correct answer is ( 1 ⁄4 # 16)
3.
22. B. Four pounds of steak at $3.89 per pound cost $15.56. Change from a $20 bill would
therefore be $ 20. 00 - $ 15.
56 or $4.44.
23. C. In the series 8, 9, 12, 17, 24, . . . , note the changes, or differences, between numbers:
9- 8=
1
12 - 9 = 3
17 - 12 = 5
24 - 17 = 7
Hence, the difference between the next term and 24 must be 9, or x- 24= 9, and x= 33.
Therefore, the next term in the series must be 33.
24. E. The total hours equals:
4+ 2+ 3+ 4+ 3=
16
Since the earnings equals the total hours times the hourly rate:
16 ($7.25)
25. C. Enlarging each dimension by 20%, or 1 ⁄5, the new dimensions would be 2.4 inches and
3.6 inches. Therefore, the new area would be 24 . # 36 . or 8.64 square inches.
26. B. In order to have the pie graph represent blue-eyed students as 6 out of 24, the piece of
the “pie” representing blue-eyed students should be 6 ⁄24 or 1 ⁄4 . So the blue piece needs to be
increased. Likewise, for hazel to represent 5 ⁄24, its piece of the pie should be slightly less
than 6 ⁄24, so its size should be decreased.

27. B. To answer this question, multiply 36 by 11 1 ⁄2. You can also change 11 1 ⁄2 to 11.5.
or
36 # 11.
5 = 414
36 # 11 1
⁄2 =
36 #
23
2 = 414
28. C. In 1970, 10% of $12,000, or $1,200, was spent on medical. In 1975, 12% of $16,000,
or $1,920, was spent on medical. Thus, there was an increase of $720.
