What is this?? CALCULUS problem??

Question

If the total weekly cost (in dollars) incurred by the Lincoln record company in pressing x long-playing records is C(x) = 1950=2.2x^2, find the marginal cost. _______

Use marginal analysis to ESTIMATE the cost incurred in producing the 1051-st record._______

What is the actual cost incurred in producing the 1051-st record._______

Answer 1

Yes, it is a calculus problem.
I don't think your function should have 2 equal signs in it - makes it difficult to solve equations properly.

Answer 2

Yeah, you had a typo.

Marginal cost is just dC/dx.

Actual cost is C (1051) - C (1050).
