High now we are going to find approximately at what price is 2500 bikes are supplied and demanded.
00:09
So now we have to find the supply and demand curve as a function.
00:16
Now here the blue line denotes the supply curve.
00:21
So from that i take two points 0, 80 and 17, 65.
00:29
Then the slope m will be equal to 65 minus 80 divided by 17 minus 0 and this will be equal to minus 15 divided by 17.
00:42
Then the equation of line with slope m is equal to minus 15 divided by 17 and passes through the point 0, 80 can be written as y minus 80 is equal to minus 15 divided by 17 into x minus 0.
01:12
So from this we get y is equal to minus 15 divided by 17 x plus 80.
01:19
Now this is the equation for supply function.
01:24
So now in part a we have to find approximately at what price is 2500 bikes supplied.
01:32
Now here the given quantity is in 1000.
01:35
So we have to put x is equal to 2 .5 in the above equation.
01:41
Then we get the price y is equal to minus 15 divided by 17 into 2 .5 plus 80 and this will be equal to 77 .7941.
01:58
Now here the price is in 100.
02:00
So we have to multiply this by 100.
02:03
Then this will be equal to 7779 .411 dollar.
02:11
Now we have to round the answer to the nearest 50 dollar...
