Question

Callaway golf Company has determined that the marginal cost C of manufacturing x Big Bertha Golf clubs may be expressed by the quadratic function: C(x) = 4.9^2 - 617.4x + 19,600

How many clubs should be produced to minimize marginal cost?

Answer 1

That's solvable easily with calculus, not sure whether you're supposed to be using it given your heading:

C'(x) = 4.9(2)x - 617
= 9.8x -617.4
at its minimum,
9.8x = 617.4
