The total cost we know per day is going to be $5 ,200.
00:08
And the total cost is going to be a mix of two different things added up together.
00:12
We're going to have some fixed cost amount, and we're going to also have some amount that depends on how many boards we output.
00:21
So varying depending on output.
00:28
And in particular here, we know that the fixed cost is 400 per day, so we'll put in 400 there for fixed cost.
00:37
And we also know that we're putting out 20 boards.
00:40
So we're going to have some cost here that's 20 times the cost per board.
00:44
So the c here represents the cost per board.
00:51
And so ultimately here, that gives us the equation, 5 ,200 equals 400 plus 20c.
00:59
And if you can solve for c, that tells us how much it costs to produce each board.
01:04
So first, i'm just going to go ahead and divide this entire equation by 10 to divide by 10 on this side and divided by 10 on this side.
01:12
That just canceled out 1 -0 from each number...
