Set up two equations: one for the amount of money collected, and one for the number of tickets sold (people who attended).
Let a= adults
Let s= students
Money equation:
Ticket equation:
Now just solve the system of equations for s:
420 Students attended
C. $122.10
20 first hour
20+0.1*20 = 22 second hour
22+0.1*22 = 24.2 third hour
24.2+0.1*24.2 = 26.62 fourth hour
26.62+0.1*26.62 = 29.282 fifth hour
Total=$122.10
Answer:
C. An increase of 20%
Step-by-step explanation:
50/100 = 60/x
Cross products
50
x = 6000
Divide 50 by both sides
x = 120
60 is 120% of 50, so there is a 20% increase
Hope this helps!

Answer:
<u><em>Observe the attached image</em></u>
Step-by-step explanation:
We have the graph of a line that passes through the points (0,5) and (2, 1).
The equation of the line that passes through these points is found in the following way:
Where
m = slope
So
We must apply to this function the transformation.
We know that a transformation of the form
shifts the graph of the function f(x) h units to the right if , or shifts the function f(x) h units towards the left if .
In this case then the transformation displaces the graph 4 units to the right.
Therefore if f(x) passes through the points (0,5) and (2,1) then passes through the points (4, 5) (6, 1)
And its equation is:

The volume of a cone whose radius is 3 1 / 2 cm and vertical height is 24 cm is 307.72 cm³
<h3>Volume of a cone</h3>
The volume of a cone can be represented as follows:
volume = 1 / 3 πr²h
where
Therefore,
r = 3 1 / 2 cm = 7 / 2 cm
h = 24 cm
Hence,
volume = 1 / 3 × π × (7 / 2 )² × 24
volume of a cone = 1 / 3 × π × 49 / 4 × 24
volume of the cone = 1 / 3 × π × 1176 / 4
volume of the cone = 1176 / 12 π
volume of the cone = 98π
volume of the cone = 307.72 cm³
