Question

For the cost function, find the marginal cost at the given production level x. State the units of measurement. (All costs are in dollars.)

C(x) = 15,000 + 70x + 1,000/x ; x = 100

Answer 1

I think I should take the derivative of the cost equation first?

Answer 2

Yeah, find C'(x) and find C'(100)

Answer 3

thanks kira :)
