This comprehensive practice examination is
designed to reflect the structure, difficulty, and
content emphasis of the WGU C957 Applied Algebra
OA. It is based on the most recent syllabus and
integrates concepts from past papers and the most
frequently tested question types. The exam covers
all major domains: Linear Functions, Systems of
Equations, Exponential and Logarithmic Functions,
Polynomials and Rational Functions, and Data
Analysis/Regression.
,Question 1
A gym charges a flat monthly fee of $30 and an
additional $5 per class attended. What is the total
cost, C, for a month in which a member attends x
classes?
A) C = 5x + 30
B) C = 30x + 5
C) C = 35x
D) C = 30x - 5
Correct Answer: A
Rationale: The flat fee is the y-intercept (30), and
the per-class charge is the slope (5). Therefore, the
linear equation is C = 5x + 30.
Question 2
What is the slope of the line passing through the
points (2, 3) and (5, 9)?
A) 1
B) 2
,C) 3
D) 1/2
Correct Answer: B
Rationale: Slope is calculated as (y2 - y1) / (x2 - x1)
= (9 - 3) / (5 - 2) = = 2.
Question 3
A company's profit P (in thousands of dollars) is
modeled by P(t) = -2t^2 + 20t - 30, where t is time in
years. What is the maximum profit the company
can achieve?
A) $20,000
B) $30,000
C) $50,000
D) $80,000
Correct Answer: A
Rationale: The maximum of a quadratic function
occurs at t = -b/(2a) = -20/(2-2) = 5 years. The
maximum profit is P(5) = -2(25) + 20(5) - 30 = -50 +
100 - 30 = 20 (thousand dollars).
, Question 4
Solve the system of equations: 2x + y = 10 and x - y
= 2.
A) (4, 2)
B) (2, 6)
C) (3, 4)
D) (6, -2)
Correct Answer: A
Rationale: Adding the two equations eliminates y:
3x = 12, so x = 4. Substituting x = 4 into x - y = 2
gives 4 - y = 2, so y = 2.
Question 5
The population of a city is 50,000 and is growing at
a rate of 3% per year. Which function represents
the population after t years?
A) P(t) = 50,000(1.03)^t
B) P(t) = 50,000(0.97)^t
C) P(t) = 50,000(3)^t
D) P(t) = 50,000(0.03)^t
