Pls mark brainliest if correct:)
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
<u>Answer</u>:

Then after three years, the resale value is
Resale Value = 
Substituting the values,
Resale Value = 
Resale Value = 
Resale Value = 
Resale Value = $632.8125
Therefore, the resale value after three years = $ 632.8125
