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%

the third answer is correct.
