# optimization of a contract length

Suppose the marginal benefit of writing a contract is $60, independent of its length. Find the optimal contract length when the marginal cost of writing a contract of length L is:

a. MC(L) = 20 + 3L

MC(L) = 50 + 4L.

Instruction: Round your answers to 2 decimal places.
