Answer:

a.  Production decreased by 4 percent

Explanation:

In 2009, production: 60,000 units

Hours worked per day: 80x8= 640 hours

Productivity= 60,000/640 hours =93.75 units per day

In 2010: production: 76 500 units

Hours worked per day= 85x10= 850 hours

productivity= 76,500/850= 90  units per day

In 2010, production decreased by 3.75 per day. (93.75-90.00)

percentage decrease= (3.75/93.75) x 100=4

In 2010 production decreased by 4 percent
