So while seeing the question let's go to the answer.
00:02
So let's see here that the price marginal cost ratio tells the markup over marginal cost.
00:36
This can be seen as below.
00:47
P by mc is equal to 94 .95 by 44 so p by mc is equal to 2 .11.
01:05
This means price is 2 .11.
01:10
This means price is 2 .11 times the marginal cost.
01:26
Learner's index can be calculated as follows.
01:51
P minus mc by p is equal to minus 1 by e.
02:02
So 1 by e is equal to 94 .95 minus 44 by 95 by 45 by 95, 95, 95, 95, 95, 95 is equal to 0 .95 is equal to 0.
02:21
5366 so the learners index is 0 .5366 elasticity is is defined as negative inverse of learner 5x index this can be calculated as follows e is equal to minus 1 by 0 .5 ,366 is equal to minus 1 .863.
03:56
Elasticity of demand is minus 1 .863.
04:13
This shows the demand is elastic...
