What information do you need to know to calculate the cost of the pizza?

To calculate the cost, first determine how many slices are needed: multiply the number of people (B) by the slices each person will eat (C). Then use the slices per pizza (F) to find how many pizzas to buy, and the price per pizza (G) to find the total cost. The party start time and drink preferences or amounts do not affect the pizza cost.
