Labor costs. A defense contractor is starting production on a new missile control system. On the basis of data collected during the assembly of the first 16 control systems, the production manager obtained the following function describing the rate of labor use: L ′ ( x ) = 2 , 400 x − 1 / 2 For example, after assembly of 16 units, the rate of assembly is 600 labor-hours per unit, and after assembly of 25 units, the rate of assembly is 480 labor-hours per unit. The more units assembled, the more efficient the process. If 19,200 labor-hours are required to assemble the first 16 units, how many labor-hours L ( x ) will be required to assemble the first x units? The first 25 units?

Solution Summary: The author explains the labor-hours required to assemble the first x units and the second 25 units. The rate of labor use is given by the function L(x).
