Solve the below problem:
Q: The management of Rocko's Pizzeria is considering a special promotion for the last two weeks of October, which is normally a relatively low-demand period. The special promotion would involve selling two medium pizzas for the price of one, plus 1 cent. The medium pizza normally sells for $12.99 and has variable expenses of $4.50. Expected sales volume without the special promotion is 600 medium pizzas per week.
