The company should produce "85" DVD's to maximize the profit.
According to the question,
The profit P for producing n DVD copies are
Let,
Now,
To find the minimize profit,
→ [tex]P'(n) = 0[/tex]
→ [tex]-0.04n+3.4=0[/tex]
By substracting "3.4" from both the sides, we get
→ [tex]-0.04n+3.4-3.4=-3.4[/tex]
→ [tex]-0.04n = -3.4[/tex]
→ [tex]n = \frac{-3.4}{-0.04}[/tex]
→ [tex]n = 85[/tex]
Thus the answer above is right.
