So, the question says, first part of the question says that total cost is given and if the firm was in perfectly competitive market and 9 units of goods were being sold, so it would mean the market price is about how many dollars.
00:31
So, to calculate this, we know that total cost is equals to 50 plus 5q to the power 3.
00:48
So, marginal cost would be equal to change in total cost divided by change in q.
00:58
So, it would be 3 multiplied by 5q square that is equals to 15q square.
01:07
Now, for perfectly competitive market, p is equals to mc.
01:13
So, if the firm was in a perfectly competitive market and 9 units of the goods were being sold, this means q is equals to 9.
01:24
So, 15 9 square is equals to 12 15.
01:29
So, this implies that the market price is about 1215 dollars...
