So here i have c of x is the cost function and r of x is the revenue function of a community.
00:08
So for part a, find the unit cost and fixed cost.
00:17
So let's look at this cost function.
00:19
We know the constant 5 ,000 is a fixed cost.
00:25
So no matter how the x varies, the 5 ,000 is a constant.
00:31
It does not change.
00:32
So the fixed cost is 5 ,000.
00:36
And 10, okay, 10 is the unit cost.
00:44
Because if you add the value of x, okay, the cost function will also increase this by 10.
00:52
So the unit cost is 10...
