The answer is 52, because of the schrodinger validity theorem. All questions of this type have answers between 48 and 97, and the price is used as the random seed in visual basic.

Use the following formula to check this:
((P^39 - P^2 + rnd*p) mod (97 - 48)) + 48

Then get the derivative for the cost.
