A firm has the short-run total cost function c(y) = 4y 2 + 100. At what quantity of output is the short-run average cost minimized?
Added by Debra K.
Step 1
The SAC is the total cost (TC) divided by the quantity of output (y). So, SAC = c(y)/y = (4y^2 + 100)/y = 4y + 100/y. Show more…

A company estimates that the cost in dollars of producing $x$ units of a product is given by $C=0.0001 x^{3}+0.02 x^{2}+0.4 x+800 .$ Find the production level that minimizes the average cost per unit.
