Hello.
00:02
For this question we need to find the average long run total cost per each quantity and in this case we will have numbers to answer this question.
00:15
So let's let's make this table we have different quantities one two three four five six seven and let's calculate the long run average total cost for three different firms firm a, b and c.
00:36
For all of them we calculate the average long run total cost by dividing long run total cost by the quantity.
00:53
Everything is given, we can easily calculate this using calculators or even without them.
01:00
So, for example, for firm a, we divide 10 by 1 and it's 10, 10 over, then 21 over 2 is 10 .5.
01:15
When 23, it's 32 over 3, which is 10 .36.
01:24
Then it will be 43 over 4, which is 1075.
01:28
Then it's 54 over 5 10 .8, 66 over 6 is 11 and 11 .43.
01:41
Similarly for firm b it will be 10, 7 .5, 6, 5 .75, then 7, 8 .33, then 7, 8 .33, and 3 3 3 .9 .29 and for firm c we have 10, 9 .5, 9 .33, 9 .25, 9 .20, 9 .20, 9 .17 and 8 .57.
02:29
And now we can answer your question.
02:33
So firm experiences economies of scale when the average total cost, which is total cost per quantity, in this case we have economies of scale...
