Here the answer.
00:03
Step 1.
00:04
The price and quantity demanded are the two components that are used to calculate the price elasticity of demand changes the quantity demanded with the change in the price level.
00:20
The quantity demanded can also be affected by other components and so the elasticity changes.
00:29
Now for the next step for the part 1.
00:31
The price elasticity can be calculated by multiplying the reciprocal of the slope that is 0 .2.
00:40
Negative sign is ignored.
00:43
With the ratio of the price and the quantity demanded.
00:47
The quantity demanded can be calculated by putting the value of price level that is rm 10 in the demand function.
00:58
So here by putting the values, we get p is equal.
01:01
To 20 minus 0 .2 q or 10 will be equal to 20 minus 0 .2 q.
01:09
Here by rearranging the equation to solve for q, we get 10 minus 20 is equal to minus 0 .2 q.
01:18
Minus 10 is equal to minus 0 .2 q.
01:22
And from here we get q is equal to minus 10 divided by minus 0 .2...
