Let p(t) be the number attendees and t be the ticket price measured in units of 10s of rupees. When the price is t = 7 (i.e. Rs70), there were p(7) = 300 people in attendance.
For each unit increase in t (i.e. for each Rs10 increase in price), p(t) is expected to fall by 20, so that
p(t + 1) = p(t) - 20
Solve for p(t). Suppose t ≥ 7. By substitution,
p(t + 1) = (p(t - 1) - 20) - 20 = p(t - 1) - 2×20
p(t + 1) = (p(t - 2) - 20) - 2×20 = p(t - 2) - 3×20
p(t + 1) = (p(t - 3) - 20) - 3×20 = p(t - 3) - 4×20
and so on, down to
p(t + 1) = p(7) - (t - 6)×20 = 420 - 20t
or
p(t) = 420 - 20 (t - 1) = 440 - 20t
With t = price per ticket (Rs/ticket) and p(t) = number of attendees = number of tickets sold, it follows that the income made from ticket sales for some fixed ticket price t would be t×p(t). If one plots p(t) in the coordinate plane, the price that maximizes income and number of attendees is such that the area of a rectangle inscribed by the line p(t) and the coordinate axes is maximized.
Let A(t) be the area of this rectangle, so
A(t) = t p(t) = 440t - 20t²
Without using calculus, complete the square:
A(t) = 440t - 20t² = 2420 - 20 (t - 11)²
This is the equation of a parabola with vertex at (11, 2420), so the optiml ticket price is Rs11, and at this price the drama club can expect an income of Rs2420.
With calculus, differentiate A with respect to t and find the critical points:
A'(t) = 440 - 40t = 0 ⇒ 11 - t = 0 ⇒ t = 11
Differentiate A again and check the sign of the second derivative at this critical point:
A''(t) = -40 ⇒ A''(11) = -40 < 0
which indicates a local maximum at t = 11 of A(11) = 2420.

find the slope
Answer:
2/3
Step-by-step explanation:
slope formula : ( y2 - y1 ) / ( x2 - x1 ) where the x and y values are derived from points on the line
the two points can vary but i have chosen (0,0) and (3,2)
(x1,y1) = (0,0) so x1 = 0 and y1 = 0
(x2,y2) = (3,2) so x2 = 3 and y2 = 2
recall that slope = ( y2 - y1 ) / ( x2 - x1 )
plug in x1 = 0, y1 = 0, x2 = 2 and y2 = 3
slope = ( 2 - 0 ) / ( 3 - 0 )
slope = 2 / 3

To determine the whether the ordered pair satisfies the equation:
⇒ we must plug in the values
⇒ since coordinates are (x,y) ⇒ (2,1)
⇒ there we must plug 2 into the 'x' position in the equation
⇒ and 1 into the 'y' position in the equation
Let's try the first equation:

A baker has 14 boxes of muffins to fill. Each box has 12 muffins. He has already boxes 45 muffins. How many more muffins does the baker need to box
Answer:
123 more muffins
Step-by-step explanation:
To find out how many to box in total you would do 14 x 12 = 168
168 - 45 = 123
Since 45 were already boxed, 123 more would be needed to make 14 boxes.

Suppose a ball rolls down the ramp shown at

the time it will take to roll from the top of the
ramp to the bottom. Round to the nearest tenth of a second.
The time it will take to roll from the top of the ramp to the bottom by the ball when acceleration of it a = 2 ft/s2, is 4 seconds.
What is the equation of motion?The equation of motion is the relation between the distance, velocity, acceleration and time of a moving body.
The equation which gives the distance d of an object starting at rest travels given acceleration a and time t is,
[tex]d = \dfrac{1}{2}at^2[/tex]
Suppose a ball rolls down the ramp shown at the right with acceleration a = 2 ft/s2. The ramp is 12 feet long. Thus, the distance travel by ball to roll from the top of the ramp to the bottom is 12 feet. Thus, we have,
[tex]a=2\rm\; ft/s^2\\d=12\rm\; feet[/tex]
Put the values in the above equation,
[tex]d = \dfrac{1}{2}at^2\\12 = \dfrac{1}{2}(2)t^2\\t^2=12\\t=\sqrt{12}\\t=3.46\\t=\approx 4\rm\; s[/tex]
Thus, the time it will take to roll from the top of the ramp to the bottom by the ball when acceleration of it a = 2 ft/s2, is 4 seconds.

#Keep LearningIn a city, 45% of the bus riders with a monthly pass are students. In a random sample of 50 bus riders with monthly passes, 18 are students.
What is ρ and ρˆ ?
ρ=0.45, ρˆ=0.18
ρ=0.45, ρˆ=0.36
ρ=0.18, ρˆ=0.45
ρ=0.36, ρˆ=0.45
Answer:
ρ =45% or 0.45
ρ with ^ = [tex]\frac{18}{50} =0.36[/tex] or equivalently 36%
Step-by-step explanation:
ρ represents the population proportion of the bus riders, with a monthly pass, who are students.
The population proportion is simply the percentage of the entire population with a particular characteristic. We have been informed that in a city, 45% of the bus riders with a monthly pass are students. This means that 45% of the whole population of bus riders with a monthly pass are students. Therefore, our ρ is simply 45% or 0.45.
ρ with ^ represents the sample proportion of the bus riders, with a monthly pass, who are students. This is a statistic or an estimator as it is normally used to estimate the value of ρ, the population proportion. It is calculated using the formula;
ρ with ^ = [tex]\frac{x}{n}[/tex]
where n represents the size of the sample and x the number of individuals in the sample with a certain desired characteristic. We have been informed that;
in a random sample of 50 bus riders with monthly passes, 18 are students.
Using the above formula and the values given we have;
ρ with ^ = [tex]\frac{18}{50} =0.36[/tex] or equivalently 36%

126 is 60% of what number
Answer:
210
Step-by-step explanation:
126 is 60% of What Number? - 126 is 60% of 210. 100% of 210 is 210, therefore 60 percent of 210 equals 126.
Formula = Number x 100
Percent = 126 x 100
60 = 210
Following shows the steps on how to derive this formula and find out 60% of what number is 126.
Step 1: If 60% of a number is 126, then what is 100% of that number? Setup the equation.
126
60% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
60Y = 126 x 100
60Y = 12600
Y = 12600
100 = 210
What is 126 % of 60 ? = 210
Answer: …
Step-by-step explanation:
Well, 126 is 60% of 210. 100% of 210 is 210, therefore 60 percent of 210 equals 126

Of this group. 1/5 of them wore glasses
If there are 33 students who wear glasses that identiñed blue as their favorite color, how many students are there in the school?
Using proportions, it is found that there are 165 students in the school.
What is a proportion?A proportion is a fraction of a total amount.
In the school, there are n students. Of those 1/5 of 3/8, that is, 3/15 wear glasses and identified blue as their favorite color. This amount is equivalent to 33 students, hence:
3/15n = 33
n = 33 x 15/3
n = 11 x 15
n = 165.
