percentage change in labor productivity = 28.23%

Explanation:

In 2009 the computer manufacturer had a labor productivity of 3.33 units per labor hour.  In 2010 the productivity increased to 4.27 units per labor hour.

The percentage change in labor productivity can be calculated  as

change in labor productivity = New labor productivity - Old labor productivity

percentage change in labor productivity = change in labor productivity/old labor productivity  × 100

Old labor productivity = 3.33 unit

New labor productivity = 4.27 unit

change in labor productivity = 4.27 - 3.33 = 0.94

percentage change in labor productivity = 0.94/3.33  × 100

percentage change in labor productivity = 94/3.33

percentage change in labor productivity = 28.2282282282

percentage change in labor productivity = 28.23%
