The first two files contain the solution of the profit maximization problem (PMP) when the prodution function is a Cobb-Douglas with increasing, constant or decreasing returns to scale. File 1 contains the two step solution to the PMP: first solve the cost minimization problem for any y to obtain the cost function, which is then used in the second step to solve the PMP. File 2 contains the 1 step (direct) solution of the PMP.

The other files contain solution topics to several exercises.
