First thing we're asked to do is find out whether this company is making a profit or a loss and how much that is.
00:08
So profit or a loss, i'm going to use pi as a symbol to represent that, is equal to total revenue minus total costs.
00:17
And total revenue in this situation is equal to the number of goods sold times the price.
00:24
So that'll be the quantity times price minus the total cost.
00:30
And the total cost we get from this table in question 7 .3.
00:38
We see that for a quantity of five, our variable cost is 100.
00:44
And our total cost is equal to variable cost plus fixed cost.
00:52
So at a quantity of five, our variable cost is $100.
00:56
And our fixed cost, because it's fixed, is always going to be, $30.
01:04
So now we just need to find out what quantity times price is.
01:08
Our price we're given in the problem is $25 and we're given that we are selling it a quantity.
01:16
We're selling five units of this product.
01:20
So our profit is going to be five times 125, which is 125 minus 100 plus 30, which is 1 .30, which is equal to negative five dollars.
01:33
So because negative five, is less than zero, they're making a loss...
