So here we're given a demand equation and a price, right? this is a very weird way to present a demand equation.
00:06
Usually they're not given like this, but that's totally fine.
00:09
We can work with it, right? it's a relationship between price and quantity.
00:15
We're given here quantity in x, and we're supposed to start off with p equals 2 and determine quantity demanded, right? so let's re we could a sub in 2 if we want and just get right to it.
00:27
3 times 2 plus 4x minus 60 is equal to 0, right? 6 plus 4x minus 60 is equal to 0.
00:38
4x minus 54 is equal to 0.
00:45
4x is equal to 54, x is equal to 13 .5, right? and that's easy enough to do.
00:54
So, and that is 13 .5 ,000.
00:57
And if you wanted to do any other price, the question maybe got cut off here a little bit, so i'm going to do a slightly different price.
01:04
Suppose that the price is now five...
