The starting price for a ticket for a high school play is $5. The auditorium capacity is 400 people. The organizer estimates that for every 10 cent increase in the ticket price 5 less people will attend the play. What is the best price and what is the maximum revenue that the school can get?
The best price is $6.50, and the maximum revenue that the school can get is $2,112.50.
Price determinationGiven that the starting price for a ticket for a high school play is $5, and the auditorium capacity is 400 people, and the organizer estimates that for every 10 cent increase in the ticket price 5 fewer people will attend the play, to determine what is the best price and what is the maximum revenue that the school can get, the following calculation must be made:
400 x 5 = 2,000395 x 5.1 = 2,014.5390 x 5.2 = 2028350 x 6 = 2100300 x 7 = 2100325 x 6.5 = 2112.5320 x 6.6 = 2112330 x 6.4 = 2112Therefore, the best price is $6.50, and the maximum revenue that the school can get is $2,112.50.

Answer:
13/24
Divide the numbers by 10.
[tex]\frac{130/10}{240/10} = \frac{13}{24}[/tex]
With that information, the answer is 13/24.
Carmen deposits $4000 into a simple interest account. The interest rate for the account is 4.25%.
Write a function that represents the balance in the account as a function of time t.
answer : f(t) = 4000 + 170t
f(t) = principal + (principal multiplied by interest rate) multiplied by time
f(t) = 4000 + (4000*.0425)t
f(t) = 4000 + 170t
t = number of years
======================================================
Explanation:
We use the simple interest formula which is
i = P*r*t
where in this case,
P = 4000 = amount deposited aka principalr = 0.0425 = decimal form of the 4.25% annual interest ratet = unknown number of yearsWe then get the following
i = P*r*t
i = 4000*0.0425*t
i = 170t
Showing that the amount of simple interest earned is 170 times that of the number of years.
For instance, if Carmen waits t = 10 years, then she earns i = 170*t = 170*10 = 1700 dollars in interest alone.
The expression 170t is the interest only. Add on the original amount deposited to find the total account balance after t years. Therefore, we arrive at 170t+4000 to get the linear function f(t) = 170t+4000
The 170 acts like the slope while the 4000 is the y intercept.

Find a whole number $a$ such that the numbers $\frac{2}{a}$ , $\frac{a}{8}$ , and $63\%$ are in order from least to greatest
If 2/a, a/8, and 63% = 63/100 are in numerical order, then
2/a < a/8 < 63/100
Multiply each "side" of the inequality by 8a :
16 < a² < 126a/25
a has to be a whole number, and since 4² = 16, we must have at least a ≥ 5.
Divide through by a :
16/a < a < 126/25 = 5 + 1/25
Then at most, a ≤ 5.
So, both a ≥ 5 and a ≤ 5, which means a = 5.
Just to check that the list is in order, we have
2/a = 2/5 = 0.4
a/8 = 5/8 = 0.625
and 0.4 < 0.625 < 0.63.

Step-by-step explanation:
1 m = 100 cm
72 m = 7200 cm
Ratio of model size to real size
18 cm : 7200 cm
Divide both numbers by 18.
1 cm : 400 cm

Answer:
A) equality function will hold
B) equality function doesn't hold
C) equality function holds )
D) equality function doesn't hold
E) equality function holds
Step-by-step explanation:
a) ⌊⌈x⌉⌋ = ⌈x⌉ for all real numbers x.
The ceiling function will yield an integer, that is greater ≥ x.
Also the floor function when applied to an integer will yield the same integer value. hence the two sides will become the same Therefore the equality function will hold
b) ⌊x+y⌋=⌊x⌋+⌊y⌋ for all real numbers x and y
The floor function of this statement yields a value that is ≤ inserted value and this makes the right hand side of the statement to be 1 less than the sum produced from the left hand side of the statement, therefore the equality function doesn't hold
c) ⌈⌈x∕2⌉ ∕2⌉ = ⌈x∕4⌉ for all real numbers x.
The ceiling function produces an integer that is ≥ value inserted and the integer gotten is divided by 2 and this serves a s an input to the ceiling function( which means X has been divide by 4 ) making the two sides of the equation the same ( equality function holds )
d)⌊√⌈x⌉⌋ = ⌊√x ⌋ for all positive real numbers x
The ceiling function is applied to the value inserted in x(on the left hand side ), and the result will not be equal to that in the right hand side.
Therefore the equality function doesn't hold
e) ⌊x⌋+⌊y⌋+⌊x+y⌋≤⌊2x⌋+⌊2y⌋forall real numbers x and y.
If the value of the fractional part of x or y is > 0.5, then the right hand side will be greater than the left hand side by 1.
Otherwise, both left and right hand sides yield equal answers. therefore equality function holds

The class scores of a history test have a normal distribution with a mean Mu = 79 and a standard deviation Sigma = 7. If Opal’s test score was 72, which expression would she write to find the z-score of her test score?.
Using the normal distribution, we got that expression for the z-score of her test score is
[tex]z= \frac{72-29}{7} \\\\z=-7/7\\\\z=-1[/tex]
What is Normal Probability Distribution?it's a type of probability distribution which is symmetric about the mean, it gives data near the mean are more frequent than data far from the mean.
Given that mean =[tex]\mu=79[/tex]

X=73
we know that formula of z-score is
[tex]z=\frac{X-\mu}{\sigma}[/tex]
Hence Z-score can be calculated as
[tex]z= \frac{72-29}{7} \\\\z=-7/7\\\\z=-1[/tex]

Step-by-step explanation:
Since the amount of hours she worked isn't a whole number, we can first separate 18 and 1/2 and work the problem out one at a time.
1. Multiply 7.20 by 18 to get 129.60
2. Multiply 0.50 by 7.20 to get 3.60.
3. Add 129.60 and 3.60 together to get the answer, 133.20.

In Fig. 7.2, a find the value of y when x = -2-5,
Answer:
Given equation: y = x² + 2x - 3
If you wish to find the values of y when x = -2 and x = -5:
When x = -2:
⇒ y = (-2)² + 2(-2) - 3
⇒ y = 4 - 4 - 3
⇒ y = -3
When x = -5:
⇒ y = (-5)² + 2(-5) - 3
⇒ y = 25 - 10 - 3
⇒ y = 12
If you wish to find the value of y when x = -2-5:
When x = -2-5 ⇒ x = -7
⇒ y = (-7)² + 2(-7) - 3
⇒ y = 49 - 14 - 3
⇒ y = 32
Answer:
y = 32
Step-by-step explanation:
Given :-
y = x² + 2x - 3
x = -2-5 = -7
To Find :-
y
Inputting the value of x :
y = (-7)² + 2(-7) - 3
y = 49 - 17
Solution :-
y = 32

A car drives 60 mph. Write and solve an eqaution to find the number of hours it takes the car to travel 360 miles.
Answer:
6 hours
Step-by-step explanation:
Let's highlight/bold some important terms.
A car drives 60 mph. Write and solve an eqaution to find the number of hours it takes the car to travel 360 miles.
So we know Speed multiplied by Time is equal to distance, or commonly known as;
S · T = D
So since we know this, we can substitute the values for the variables.
We know the mph is 60. And that's our speed.
The equation is now 60 · T = D
We know that the total distance the car needs to cover is 360.
The equation is now 60 · T = 360
Now we need to find the time it took.
We divide 360/60 to find out the total number of hours it took, and we get 6.
So the answer is that it took 6 hours to travel 360 miles with a speed of 60 mph.
Answer:
6 hours
Step-by-step explanation:
The lines are parallel. Find x.
Answer:
As the lines are parallel, it shows that the two lines form 180° because they are angles on the same side of the transversal. A transversal is a line that bisects two lines.
Here,
(20x + 5)° + (24x - 1)° = 180°
=> (20x + 24x)° + (5 + (-1) )° = 180°
=> 44x° + 4° = 180°
=> 44x = (180 - 4)°
=> x = 176 / 44
=> x = 4
Therefore, x = 4 is the solution of the equation.
