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
