2. Based on the table below, do the following analysis:

Output(Y)	Total Cost(TC)	Marginal Cost(MC)
1	$210	(1)
2	$340	(2)
3	$490	(3)
4	$660	(4)
5	$850	(5)
6	$1,060	(6)
7	$1,290	-

2-1. Calculate Marginal Cost(MC) for (1) - (6) .

2-2. Draw a curve of TC and a curve of MC, by dot plotting. (Hint: refer to slide 32, 33 and 39 of Ch13 PPT.)

2-3. Denote the "efficient scale" on the graph you draw from the above step 2-2.

2-4. Look at the MC curve, describe its pattern, then give an explanation on why it is rising eventually.

(no need for explanations, Thank you)
