Club Members = $25 + $7 per movie(x)
No membership club = $12 per movie(x)
We need to know how many movies must each purchase to equal in costs.
Set up both equations to equal each other and solve for x=movies.
25 + 7x= 12x
25 + 7x -7x = 12x - 7x
25= 5x
25/5=5x/5
5=x it will take them both 5 movies each to have equal costs.
The mean is the average, which is adding all the numbers up and dividing by how many numbers there are. There are 2x(1), 3x(2), 9(3), 9(4), and 5(5).
2+6+27+36+25 = 96.
There were 28 total.
Divide 96 by 28. 3.4 is the average.
The median is the middle number from least to greatest.
3.5 is the median.
The population starts at 2000, so a=2000.
We also know that the population in 3 hours is 1000, so we can setup the equation:
2000 b^3 = 1000
This gets us:
b^3 = 1/2
And taking the cube root of both sides gives us:
b ≈ 0.7937005259841
Rounding that to 4 places, we have:
f(t) = 2000 (0.7937)^t
A) L = 5 * W
B) L * W = 320
Substituting A) into B)
B) 5 * W * W = 320
5W^2 = 320
W^2 = 64
Width = 8
Length = 40
