WGU Applied Algebra FXO2 PFXP C957 Sample Questions (Q46-Q51):

NEW QUESTION # 46
A coach is placing an order for team shirts. The graph shows the total cost based on the number of shirts.

What is the cost of each additional shirt?

A. $3.30
B. $17.30
C. $14.00
D. $47.00

Answer: C

Explanation:
This question asks for the cost of each additional shirt, which means we need to find the rate of change of the linear function.
On a graph, the rate of change is the slope:
" slope " = " change in total cost " / " change in number of shirts "
From the graph, two labeled points are:
(0#33)
and
(10#173)
This means:
When 0shirts are ordered, the cost is $33.
When 10shirts are ordered, the cost is $173.
Now find the slope:
m=(173-33)/(10-0)
m=140/10
m=14
So the cost increases by:
$14
for each additional shirt.
The $33represents a fixed starting cost, not the cost per shirt.

NEW QUESTION # 47
A vehicle is travelling away from a rest stop. The function
D(t)=48t+23
represents the distance from the vehicle to the rest stop at time t, where t is measured in hours and D is measured in miles.
What is the value of D(1.7)?

A. 87.1
B. 0
C. 104.6
D. 58.6

Answer: C

Explanation:
The function is:
D(t)=48t+23
This is a linear function because it has the form:
D(t)=mt+b
where:
48
is the rate of change, and:
23
is the starting distance from the rest stop.
We need to find:
D(1.7)
That means substitute:
t=1.7
into the function.
D(1.7)=48(1.7)+23
First multiply:
48(1.7)=81.6
Now add 23:
D(1.7)=81.6+23
D(1.7)=104.6
So the vehicle is:
104.6 miles
from the rest stop after 1.7 hours.

NEW QUESTION # 48
The function P(t)represents the daily profit, in hundreds of dollars, for a museum since opening. The graph of P(t)is shown.

What is the correct interpretation of the maximum value?

A. Approximately 9.5 years after opening, a maximum daily profit of approximately $299was earned.
B. Approximately 20 years after opening, a maximum daily profit of approximately $1,650was earned.
C. Approximately 9.5 years after opening, a maximum daily profit of approximately $1,650was earned.
D. Approximately 20 years after opening, a maximum daily profit of approximately $299was earned.

Answer: C

Explanation:
The graph shows a curved, downward-opening function. This type of graph is commonly associated with a quadratic polynomial function.
The maximum value of a downward-opening parabola occurs at its highest point, called the vertex.
From the graph, the highest point occurs at approximately:
t=9.5
This means the museum reaches its maximum daily profit approximately:
9.5 " years after opening "
The vertical axis represents daily profit in hundreds of dollars. From the graph, the maximum P(t)-value is approximately:
16.5
Since the profit is measured in hundreds of dollars:
16.5×100=1650
So the maximum daily profit is approximately:
$1,650
Therefore, the correct interpretation is:
" Approximately 9.5 years after opening, a maximum daily profit of approximately " $1,650 " was earned. "

NEW QUESTION # 49
The number of letters processed daily at a mail center is modeled by the decreasing exponential function shown in the graph.

What is the long-term trend in the number of letters processed per day, based on the equation of the horizontal asymptote?

A. 2,250
B. 0
C. 4,500
D. 1,000

Answer: D

Explanation:
In an exponential decay model, the horizontal asymptote represents the long-term value that the function approaches as time increases. The graph shows the number of letters processed per day decreasing quickly at first and then leveling off. Since the graph approaches the horizontal line y=1000, the long-term trend is 1,000 letters per day. This does not mean the mail center immediately processes exactly 1,000 letters, but it means the model predicts the daily number will get closer and closer to 1,000 over time. The other choices either represent values too low or values from earlier parts of the graph, not the asymptote. Therefore, the correct answer is B.

NEW QUESTION # 50
The number of employees under supervisor B is 13 more than the number of employees under supervisor A.
Let F(n)represent the number of employees under the two supervisors, where nis the number of employees under supervisor A and Fis the number of employees under supervisor B.
Which is the correct function to represent this relationship?

A. F(n)=n-13
B. F(n)=n/13
C. F(n)=n+13
D. F(n)=13n

Answer: C
