b) Discuss the relationship between ATC and MC. Also draw a graph showing both curves.

Solutions

Expert Solution

The formula's to calculate AFC, AVC, ATC, MC are as follows:

TCn - TC n-1

TFC = $400 (becuase at output = 0 all costs are fixed costs and variable cost = 0 )

at 0 output fixed cost is not defined.

Output Total cost AFC AVC ATC MC
0 400 not defined not defined not defined not defined
10 540 400/10 =40 140/10= 14 540/10= 54 540-400=140
20 620 400/20 = 20 220/20= 11 620/20= 31 620-540= 80
30 810 400/30 = 13.33 410/30= 13.66 810/30= 27 810-620= 190
40 910 400/4= 10 510/40= 12.75 910/40= 22.75 910- 810= 100

B) As quantity increases, ATC will decrease and MC will initially decrease and then increase. Eventually they intersect, then MC continues to increase and pulls ATC up after it. A firm's marginal cost curve also acts as its supply curve. I have shown all the average cost curves along with their intersectionality in one daigram. this will help you develop better analysis of the topic.
