Question 4
Doug Walker's long run daily total cost function for
providing dog walking services is
$C(y) = 64 + 4y + y^2$
, for all
$y > 0$
, where
$y$
is hours per day of dog walking services provided, and
$C(0) = 0$
Thus, in the long run, the $64 cost is an overhead
cost that is avoided if Doug chooses not to provide
any dog walking services on a given day.
What is the lowest market price for an hour of dog
walking services that would induce Doug to provide
dog walking services in the long run?
