Problema Solution
The profit P(in millions of dollars) for a manufacturer of MP3 players can be modeled by P=-4x^3+12x^2+16x where x is the number of MP3 players produced(in millions). Currently, the company produces 3 million MP3 players and makes a profit of $48,000,000. What lesser number of MP3 players could the company produce and still make the same profit?
Answer provided by our tutors
Take,48 = -4X^3+12X^2+16X
Solving this , we get x= 3,2,-2
-2 is meaningless.
3 is given.
So by selling 2 million, we get the same profit.
So, by selling 1 million less, we can make the same profit.
