But i told the manager of an apartment complex has 100 units.
00:06
And he knows from experience that all units will be occupied if the rent is $800 per month.
00:12
So if he sets the price at this, he'll have all units occupied.
00:17
But he knows that if he addition, that on average, there'll be one additional unit vacant.
00:27
One unit will remain vacant.
00:29
For each $10, he increases.
00:32
So that means the slope of our demand curve is minus 10.
00:38
So for every increase, if we, if we lose one, if we have one extra unit free, where our price, let's see here, what did i do this way? this is a number of units.
01:01
And so, oh yeah, if we have, you know, this is 101, then this will go down, but this will go up by 100.
01:10
No, sorry, 10.
01:12
So, oh, no, this is 99.
01:15
So again, we can see here how our price, if we increase the price, our number of units goes down...
