find the marginal cost function

Question

Find the solution to C(x)=175 + 1.3x

Answer 1

Generally, MC = dC/dx = 1.3 in this case.

If you aren't doing calculus, then you should know that the slope is the MC for a linear cost function.

y = mx + b slope is m

C = 1.3x + 175 slope is 1.3

Hope that helps.
