Alright, let's do this example. The graph below represents the market for funky fresh rhymes. So, at a price of $3,000 per funky fresh rhyme, what is the producer surplus? Right. So we dealt with this graph with consumer surplus. Now we're talking about producer surplus. Okay? So how do we see what the producer surplus is in this case? Remember, producer surplus is going to be the area below the market price and above the supply curve, okay? So what is our market price here? $3,000 right here, right? So what's the area below the $3,000? It's going to be everything here, but above the supply curve right so we're going to stop when we reach the supply curve and that's going to be our producer surplus in this case is that triangle right. So we need to find the area of this triangle. If you remember, the area of a triangle is going to be half times base times height. Right? Half bh. So we need to find what the base is and what the height is, and then we can calculate this. So I tend to always put my base on the up-down axis. It doesn't really matter which one you call base, which one you call height, you'll get the same answer. So that's our base and our height there. Right? So let's go ahead and see how do we calculate the base. Well, the base is going to be this length right and it doesn't go all the way down to the bottom. It only goes up it stops at that 500 point, right, so it goes from 500 up to 3,000. So we need the distance between that and we're going to get half times so the base is going to be the difference of those two, right? 3,000 minus 500. That's going to give us the length of this. 3,000 minus 500 is the length of the base there, and let's do the same thing with height. What do we see with height? Well, it starts at 0 so we're not going to have a subtraction here. It starts all the way at 0 and it goes to this point 750. So the height is just going to be 750 in this case times 750. Alright. So we've got all our numbers. We just got to do some quick arithmetic and we'll have our area which is our Producer surplus. So half ×2,500×750. So our area is going to be let me do some quick math in my head. It's going to be 937,500 right. I did that all in my head real quick. I'm just kidding, but the idea here is right we'll do that math half ×2,500×750 and that is our producer surplus right. 937,500 and that is here at a price of $3,000 producer surplus. A $937,500. Cool. Let's move on to the next problem.
