Explanation:

Giving the following information:

Carbondale Casting produces cast bronze valves on a 10-person assembly line.

160 valves are produced during an 8-hour shift.

A) labor productivity = number of unit/number of hours = 160/8 = 20 units per hours

B) labor productivity = number of unit/number of hours = 180/8 = 22.5 units per hours

C) %of productivity increase = (22.5/20) - 1 = 0.125 = 12.5%
