Answer:
1
x
−
5
Explanation:
The key realization is that our denominator fits the difference of squares pattern
a
2
−
b
2
, which factors as
(
a
+
b
)
(
a
−
b
)
.
We can rewrite
x
2
−
25
as
(
x
+
5
)
(
x
−
5
)
, which allows us to rewrite our original expression as
x
+
5
(
x
+
5
)
(
x
−
5
)
The
x
+
5
terms on the top and bottom cancel, and we're left with
x
+
5
x
+

(
x

)

The revenue is given by the unit price * number of units.
Profit = Revenue - Cost = 200x - 500,000 - 80x - 0.003x^2 = 120x - 500,000 - 0.003x^2
For profit to be maximum dP/dx = 0
120 - 0.006x = 0
x = 120/0.006 = 20,000
Therefore, to maximize profit, the firm should produce 20,000 penicillin.
