Carbonale Castings produces cast bronze valves on a 10-person assembly line. On a recent day, 160 valves were produced during an 8-hour shift. The productivity of the line is valves per hour. John Goodale, the manager of Carbondale, changed the layout and was able to increase production to 180 valves per 8-hour shift. The new productivity is valves per hour. The % productivity increase is %. Round all answers to 2 decimal places.

Missing word " Calculate the labor productivity of the line. b) John Goodale, the manager at Carbondale, changed the layout and was able to increase production to 180 units per 8-hour shift. What is the new labor productivity per labor-hour? c.) What is the percentage of productivity increase?"

a) Output = 160 valves

Input = 10*8 = 80 labor hours

Productivity = Output / Input

Productivity = 160/80

Productivity = 2 valves per labor hour

b) Output = 180 valves

Input = 10*8 = 80 labor hour

Productivity = Output/Input

Productivity = 180/80

Productivity = 2.25 valves per labor hour

c) Percentage increase in the productivity = [(2.25 - 2) / 2] * 100

Percentage increase in the productivity = 0.125 * 100

Percentage increase in the productivity = 12.5%
