A local cinema found that if the price of admission was $17the attendance was about 1900 customers per weekWhen the price of admission was dropped to $9. Attendance increased to about 3050 per week. Write a equation for the attendance in terms of the price. P i (A=mp+b )
Answers
Answer:
f(A)= -143.75p + 4343.75
Step-by-step explanation:
Let price be x, and attendance, y
According to the given data,
admission was $17 the attendance was about 1900 customers
admission was $9 the attendance was about 3050 customers
Therefore, the points in terms of e and y coordinates would be , (17, 1900) --> (x1,y1)
& (9, 3050)---->(x2,y2)
Next is to calculate slope of linear equation i.e
m= (y2-y1)/(x2-x1)
m=(3050-1900)/(9-17)
m= -143.75
Now in order to find the equation, we use point-slope
y-y1= m (x-x1)
considering the coordinates (17, 1900) and slope -143.75
Equation becomes
y-1900 = -143.75( x- 17)
y-1900= -143.75x + 2443.75
y= -143.75x + 4343.75
or can be written as,
f(A)= -143.75p + 4343.75
Answer:
Step-by-step explanation:
From the question, A local cinema found that if the price of admission was $17the attendance was about 1900 customers per weekWhen the price of admission was dropped to $9. Attendance increased to about 3050 per week. Write a equation for the attendance in terms of the price. P i (A=mp+b )
Let price be a,and attendance, b
Attendance: 1,900 customers, when PRICE = $17
Attendance: 3,050 customers, when PRICE = $9
We then get the points,
(17, 1,900) & (9, 3,050)
Slope of linear equation,
(17,1900) (9, 3050)
find the slope m
(3050-1900)/(9 - 17)
1150/-8
-143.75=m
A=mp+b
A=-143.75p+b
using Attendance as a function of ticket price.
A(p) = mp + b
We have two points (p, A): (17, 1900), (9, 3050)
Slope: m = (2800-1500)/(7-17) = 1300/-10 = -130
A = -130p + b
Using (17, 1900) as (p, A) find b
1900 = -143.75(17) + b
1900 = -2443.75 + b
4343.75 = b
A = -143.75p + 4343.75

(note: When you move one thing to the other side of the equation, make sure to do the opposite of the sign. i.e. if it is +26 when you move to the other side it will be -26).
25d-16=4d+26
25d-16+16=4d+26+16
25d=4d+26+16
25d-4d=4d-4d+26+16
25d-4d=26+16
21d=42
this is the same as:
21*d=42
the opposite of multiply is divide so when we move the 21 it has to be divide
21/21*d=42/21
d=2
25d - 4d = 26+16
21d = 42
d = 42/21
d = 2 :)))
