21. D. The highest average daily temperature during the dates shown was approximately 76°.
The lowest was approximately 58°. Therefore,
76°– 58° = 18°.
22. E. Total number of different combinations (“how many different kinds”) is found by multiplying
the number of ways for each item. Therefore, 3 different breads times 4 different
meats times 3 different cheeses = 3# 4#
3= 36.
23. D. Since there are 6 half-shaded squares and 2 fully shaded squares, you have a total of 5
fully shaded squares. Each square is a 2# 2, so the area of each square is 4 square inches.
5# 4=
20
24. E. To determine the amount of paint used, you need to know the number of rooms painted
and how many gallons were used in each room. Since the question itself provides the
number of rooms painted, choice E provides the necessary information: number of rooms
× number of gallons used = total number of gallons used
25. E. To answer this question, subtract the distance Shalla walked from the distance Theo
walked:
6 1 ⁄4 = 5 5 ⁄4
–4 3 ⁄4 = –4 3 ⁄4
6
⁄4 = 1 2 ⁄4 = 1 1 ⁄2
Another way to approach this is to change each mixed fraction to an improper fraction,
then subtract and reduce your answer.
6 1 25
⁄4 = ⁄4
– 4 3 ⁄4 = – 19 ⁄4
6
⁄4 = 1 2 ⁄4 = 1 1 ⁄2
26. C. Substituting the given values into the equation:
I=
Prt
$ 500 = ^2000h^. 10h^th
500 = ^200h^th
500/ 200 = t
25= . t
