1. Correct answer: (C)

1 package contains 12 rolls
Other packages contain 8 rolls
She bought 5 packages

To find:
The number of rolls purchased

She bought 5 packages: 1 package with 12 rolls and 4 packages with 8 rolls.

1 × 12 + 4 × 8 = 12 + 32 = 44

Answer: (C) 44

2. Correct answer: (D)

A, B and C are points on a line in that order.
AB = 30
BC is 20 more than AB

To find:

AB = 30.

BC is 20 more than AB; BC = 20 + 30 = 50

AC= AB + BC = 30 + 50 = 80

Answer: (D) 80

3. Correct answer: (C)

x + 3 = a

To find:
2x + 6

2x + 6 = 2(x + 3) = 2a

Answer: (C) 2a

4. Correct answer: (A)

The graph

To find:
The student whose change from Test I to Test II is the greatest

The x-coordinate of a point represents the score on Test I.

The y-coordinate of a point represents the score on Test II.

We can calculate the difference between the x and y coordinates to determine the change in scores.

Point A is (40, 70), 70 – 40 = 30

Point B is (40, 60), 60 – 40 = 20

Point C is (60, 70), 70 – 60 = 10

Point D is (80, 80), 80 – 80 = 0

Point E is (80, 60), 80 – 60 = 20

The point with the greatest difference is A.

Answer: (A) A

5. Correct answer: (C)

The graph

To find:
Average of the scores of the 5 students on Test II

Topic(s): Statistics

To get the average of the scores of 5 students on test II, add up all the scores of Test II (which is the y-coordinates of the points) and divide by 5

Answer: (C) 68
