Suppose the labor cost (in dollars) for manufacturing a precision camera can be approximated by

where x is the number of hours required by a skilled craftsperson and y is the number of hours required by a semiskilled person. Find values of x and y that minimize the labor cost. Find the minimum labor cost.
