Question 734631
{{{P(x)  =   x^3  - 47x^2 - 148x -100}}} 
to find the zeros, you must apply the "rational root theorem".
That is, use synthetic division to find zeros.
After doing the above, the factors are:
P(x) = (x+2)(x+1)(x-50)
x = {-2, -1, 50}
We can ignore the negative roots.
Find the number of frames that must be sold per month for the profit to be zero.
Profit will be zero when 
50 frames are sold
.
For what x-values will the profit be positive?
x > 50
