Option B is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of students = 480
Lowest ticket price = $3
Ticket price = $4.20
This means,
4.20 - 3 = 1.20
There is an increase of $1.20 which is 0.20 x 6 = $1.20.
The number of students who attended when the ticket price is $4.20.
= 480 - (6 x 20)
= 480 - 120
= 360
Profit:
= 360 x 4.20
= $1512
Ticket price = $3.90
This means,
3.90 - 3 = 0.90
There is an increase of $0.90 which is 0.20 x 4.5 = $0.90.
The number of students who attended when the ticket price is $3.90.
= 480 - (4.5 x 20)
= 480 - 90
= 390
Profit:
= 390 x 3.90
= $1521
Now,
Ticket price = $3.50
This means,
3.50 - 3 = 0.50
There is an increase of $0.50 which is 0.20 x 2.5 = $0.50.
The number of students who attended when the ticket price is $3.50.
= 480 - (2.5 x 20)
= 480 - 50
= 430
Profit:
= 430 x 3.50
= $1505
Now,
Ticket price = $4.00
This means,
4 - 3 = 1
There is an increase of $1 which is 0.20 x 5 = $1.
The number of students who attended when the ticket price is $4.20.
= 480 - (5 x 20)
= 480 - 100
= 380
Profit:
= 380 x 4.20
= $1520
We see that,
The profit is highest when the ticket price is $3.90.
Thus,
$4 ticket price will maximize the student council's profit.

The ratio of three numbers is 4 : 5 : 3. The sum of the numbers is 54. List the numbers in ratio form.
Answer:
13.5 : 18 : 22.5.
Step-by-step explanation:
let the numbers be 3x , 4x and 5x
3x+ 4x + 5x = 54
12x = 54
x = 4.5
so the numbers are 3*4.5, 4 * 4.5 and 5 * 4.5
= 13.5, 18 and 22.5.
The list of the numbers in ratio form is 18 : 22.5 : 13.5
Given the ratio of three numbers as 4 : 5 : 3
Total ratio = 4 + 5 + 3
Total ratio = 12
If the sum of the numbers is 54.
For the ratio of 4:
= 4/12 * 54
= 1/3 * 54
= 18
For the ratio of 5:
= 5/12 * 54
= 270/12
= 22.5
For the ratio of 3:
= 3/12 * 54
= 1/4 * 54
= 13.5
Hence the list of the numbers in ratio form is 18 : 22.5 : 13.5

My homework says, "Does the graph represent a proportional relationship? Why or why not? You MUST explain to get credit."
Answer:
No, the graph does not represent a proportional relationship. It is a straight line, but it does not intersect the point (0, 0). ... It's not proportional because the line does not cross through the origin. Therefore the ratio of x to y will be different for two different points on the line.
Three students have started a fence-painting business. Working together, Pragnesh and Qazi can paint the fence in 2 hours. Similarly, Pragnesh and Ronghui can paint the fence in 3 hours when they work together. Finally, when Qazi and Ronghui work together, they can paint the fence in 4 hours. How long would it take if all three students worked together to paint the fence
Answer: 55.4 mins
Step-by-step explanation:
pragnesh and qazi = 2hrs
pragnesh and roghui = 3hrs
qazi and roghui = 4hrs
this means for every 1 hour they wold paint.
pragnesh and qazi = [tex]\frac{1}{2}[/tex] half of the fence
pragnesh and roghui = [tex]\frac{1}{3}[/tex]
qazi and roghui = [tex]\frac{1}{4}[/tex] quarter of the fence

= [tex]\frac{1}{2}[/tex] + [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{4}[/tex]

The domain for f(x) and g(x) is the set of all real numbers.
Let f(x) = 3x + 5 and g(x) = x2.
Find f(x) + g(x).
Answer:
f(x) + g(x) = x^2 + 3x + 5
Step-by-step explanation:
In order to do this, you need to substitute f(x) for 3x +5 and substitute g(x) for x2 (which I'm assuming is x squared, which I will be wrIting as x^2. If this is not the problem, please correct me)
f(x) + g(x) = 3x + 5 + x^2
Now, you need to put the varibles in decreasing order of exponents.
f(x) + g(x) = x^2 + 3x + 5
Answer:
Step-by-step explanation:
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

This is for regular Geometry.
Situation:
A 33 gram sample of a substance that's
used to detect explosives has a k-value
of 0.1473.
N = Noe
-kt
No = initial mass (at time t = 0)
N = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days
Find the substances half life, and days. Round your answer to the nearest 10th
Answer:
Half life = 4.7 days
Step-by-step explanation:
Formula to get the final amount of the substance after the time 't',
[tex]N_t=N_0e^{-kt}[/tex]
Here, [tex]N_t[/tex] = Final amount of the substance
[tex]N_0[/tex] = Initial amount
k = decay constant
t = Duration or time
Now by substituting the values in the formula,
[tex]N_t=N_0e^{-0.1473t}[/tex]
If [tex]N_t=\frac{1}{2}(N_0)[/tex] [For half life]
[tex]\frac{1}{2}(N_0)=N_0e^{-0.1473t}[/tex]
[tex]\frac{1}{2}=e^{-0.1473t}[/tex]
[tex]2=e^{0.1473t}[/tex]
ln(2) = [tex]\text{ln}(e^{0.1473t})[/tex]
0.69315 = 0.1473t
t = 4.71 days
t ≈ 4.7 days
Therefore, half life of the substance is 4.7 days.
