C(q) = 500 + 2q +1/5q2.

The marginal cost MC(q) equals the instantaneous rate of change of the total cost.

Find the marginal cost when a quantity of 10 items are being produced.

**Damon**, Sunday, February 7, 2010 at 12:05pmassume you mean:

C(q) = 500 + 2q +(1/5)q^2

dC/dq = 2 + (1/5) 2 q

= 2 + (2/5) q

when q = 10 this is

2+4

= 6 = cost of 11th item
