The first thing i needed to do is find the equation of the marginal revenue function
What i have done so far:
found slope which is -0.2
y intercept is 100
Therefore marginal revenue function is R'(x)=--0.2x + 100
However my prof tells me she wants me to find it as a definite integral with limit 0 to 1000.
Would I start the integral as
∫(100 - 0.2x)dx [0,1000]
and finish with
= 100x -0.1x^2 + C [0,1000]
