Question 422376
A company that manufactures bicycle frames has determined that the monthly profit (in dollars) from the sale of x frames is given by
P(x) = – 0.05x^3 + 1.5x^2 + 5x – 13000
----------------
Find the number of frames that must be sold per month for the profit to be zero.
Solve: – 0.05x^3 + 1.5x^2 + 5x – 13000 = 0
Ans: I graphed it and found no Real Number solutions.
----
For what x-values will the profit be positive? 
Ans: none
