Step-by-step explanation:
Cost to make the film : $6500
Cost to set up production: $1500
Additional cost to make each video : $4
Additional cost to make n videos : $4n
total cost to make n videos = $6500 + $1500 + $4n = (8000 + 4n) dollars
overall cost to make each video
= total cost to make n videos ÷ n videos
= (8000 + 4n) / n
by definition, in order to "break even", the selling price for each video must be equal to the cost to make each video. i.e
Price, P(n) = (8000 + 4n) / n
Hence,
P(500) = [8000 + 4 (500)] / 500 = (8000 + 2000) / 500 = $20
This means that in order to break even selling 500 DVD's he has to sell each one for $20
Answer
Find out the how many ping pong balls would fit inside the Earth.
To prove
Let us assume that the number of ping pong would fit inside the Earth be x.
As given
A ping pong ball has a volume of approximately 3.4 cm³.
The Earth has a volume of approximately 
cm³ .
Than the equation becomes
(approx)
Therefore in 
(approx) ping pong balls would fit inside the Earth.
