Answer: 7
Step-by-step explanation:
Well, the square root of 82 is an irrational number, so
it can never be completely written with digits. As a
decimal, it goes on and on forever, and never ends.
As a fraction, it can't be written at all.
The square root of 82 is approximately 9.055 .
(That number is about 0.0043% too small, which is pretty close.)
R(x) = 60x - 0.2x^2
The revenue is maximum when the derivative of R(x) = 0.
dR(x)/dx = 60 - 0.4x = 0
0.4x = 60
x = 60/0.4 = 150
Therefore, maximum revenue is 60(150) - 0.2(150)^2 = 9000 - 4500 = $4,500
Maximum revenue is $4,500 and the number of units is 150 units
