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

L(x,y)=3/2x^2+y^24x4y2xy+104

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.

Labor cost will be minimized when x=___ and y=___

The minimum labor cost is $___
