Consider the following cost information for a pizzeria:

Quantity	Total Cost	Variable Cost
(Dozens of pizzas)	(Dollars)	(Dollars)
0	320	0
1	380	60
2	430	110
3	460	140
4	500	180
5	550	230
6	620	300

The pizzeria’s fixed cost is.

Complete the third column of the following table by calculating the marginal cost per dozen pizzas using the information on total cost. Then complete the final column by calculating the marginal cost per dozen pizzas using the information on variable cost.

Quantity	Total Cost	Marginal Cost	Variable Cost	Marginal Cost
(Dozens of pizzas)	(Dollars)	Using Total Cost	(Dollars)	Using Variable Cost
		(Dollars)		(Dollars)
0	320		0
1	380		60
2	430		110
3	460		140
4	500		180
5	550		230
6	620		300
