Homework Statement
For a certain product, cost C and revenue R are implicitly given as follows, where x is the number of units sold (in hundreds)
a) Find and interpret the marginal cost dC/dx at x=5
b) Find and interpret the marginal revenue dR/dx at x=5
Homework Equations
C2 = x2+100√x +50
900(x-5)2 + 25R2 = 22500
The Attempt at a Solution
So I think I'm making this out to be a lot harder than it actually is. My first instinct would be to apply derivatives and chain rule.
