The revenue is 


    R(x) = x*(45-0.0125x) dollars.


This formula represents  a quadratic function, whose plot is a parabola opened downward.


It gets the maximum at the value of x which is exactly midway between the x-intersections.


The x-intersections are  x= 0  and  x= 45%2F0.0125 = 3200,

so the maximum of the function is at  x= 1600,


To get the value of the maximum, substitute  x= 1600 into the Revenue formula


    R%5Bmax%5D = 1600*(45-0.0125*1600) = 40,000 thousand dollars.    ANSWER

Solved.
