00:01
So the key principle here be that fixed costs do not affect marginal costs.
00:05
And since we have that profit maximizing output occurs where price is equal to marginal cost, the output level remains unchanged.
00:15
However, the total profit falls as fixed cost rises because we have that profit is equal to total revenue minus total variable costs plus fixed cost.
00:30
Now using the table, we're going to assume the profit maximizing output where p is equal to mc is $60.
00:38
It's going to be at six units.
00:40
We then have the compute total profit for each fixed cost level.
00:47
And we have that at six units with the price is 60.
00:51
Total revenue is then six times 60, so 360.
00:55
And then the total cost is equal to the tbc plus the fixed cost.
01:01
So we have here the tpc at 2 equals 6 is 220.
01:06
So then the profit is going to be the 360 minus the total cost of 320, which is going to be 40...
