Question

Here's another one that I do not really understand.

A company estimates that the cost (in dollars) of producing x units of a certain product isgiven by: C=800 + .04x + .0002x^2. Find the production level that minimizes the average cost per unit.
You have a typo. There is no minimum of the function you typed for positive x
dC/dx = 0 at max or min
dC/dx = 0 = .04 + .0004 x
revenueR(x)=10(x) and cost c(x) =2.5x + 1200. how many units must be produced each month to breakeven?
