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. Calculate the total contribution margin generated by the normal volume of medium pizzas in a week. (Do not round your intermediate calculations. Omit the "tiny_mce_markerquot; sign in your response.) Calculate the total number of medium pizzas that would have to be sold during the 1-cent sale to generate the same amount of contribution margin that results from the normal volume. (Do not round your intermediate calculations.)
