Okay, so we're given our marginal cost function.
00:03
Well, that's the derivative of our cost function is equal to this equation here.
00:08
And we're given that 10 units cost, cost, $94 .20.
00:12
So that means our cost function, evaluated at 10, is equal to 94 .20.
00:18
So what we can do to find our cost function is we can take the integral of our marginal cost.
00:26
And that would give us our cost function plus some constant.
00:31
Or not supposed to be this is our cost function.
00:35
So let's solve for our cost function.
00:37
So that's the integral of 5x minus 1 over x dx.
00:43
Using our difference rule, we can split that up into two integrals...
