SAT Practice Test 8, Section 2: Questions 1 - 5


This is for SAT in Jan 2016 or before.



1. Correct answer: (E)

Total cost of 3 pencils is $4.50
The cost per pencil is increased by 50 cents

To find:
The cost of 5 pencils at the new rate

Topic(s): Integer word problem

First, we find original price of one pencil.
$4.50 ÷ 3 = $1.50

New price of each pencil = $1.50 + $0.50 = $2.00

5 pencils will cost $2 × 5 = $10

Answer: (E) $10.00

2. Correct answer: (E)

A table representing the relationship between x and y

To find:
The linear equation that describes the relationship

Topic(s): Coordinate geometry

First, we have to determine the slope.

slope =

Next, we need to determine the y-intercept i.e. when x = 0

The equation is then y = 4x − 1

Answer: (E) y = 4x − 1

3. Correct answer: (B)

The figure
The two circles are tangent at point B
AC = 6
The circumference of the circle with center A is twice the circumference of the circle with center C

To find:
The length of

Topic(s): Circumference of circle

The formula for circumference of a circle is C = 2πr

So, the radius is directly proportional to the circumference.

If the circumference of the circle with center A is twice that of the circumference of the circle with center C then the radius AB will be twice that of radius BC
AB = 2BC

Given AC = 6
AC = AB + BC = 6
2BC + BC = 6
3BC = 6
BC = 2

Answer: (B) 2

4. Correct answer: (B)


To find:
The lettered points in the figure that has coordinates (x, y)

Topic(s): Absolute value

Answer: (B) B

5. Correct answer: (D)

A chart that shows the ages of 1000 people

To find:
The number of people with ages < 40

Those people with ages < 40 are in the groups x < 20 (30%) and 20 ≤ x < 40 (20%)

30% + 20% = 50%
50% of 1000 = 0.5 × 1000 = 500

Answer: (D) 500
