Okay, here we have our supply equation and our demand equation.
00:07
And if the price of the item is $50, let's find the supply.
00:13
That would be 15 times 50, and that would be 750.
00:20
And let's find the demand, 12 -493 minus 50 times 50, and that works out to be 9 ,993.
00:35
So the demand is much higher than the supply, so there is a shortage.
00:45
Now we triple the price and the price is now $150.
00:48
So the supply would be 15 times 150, and that's 2 ,250.
00:58
And the demand would be 12 ,493 minus 50 times 150.
01:07
And that is 4 ,993.
01:11
So the supply is still lower than the demand, so there's still a shortage.
01:18
Okay, for part b, we're going to figure it out, if the price is $200.
01:23
So the supply is going to be 15 times 200, and that's 3 ,000.
01:34
And the demand is going to be 12 ,493 minus 50 times 200.
01:47
And that is 2 ,493...
