Answer 1

Answer to Part (1)
Industry Sales (2011)	17210000
Industry Sales (2010)
	14437919

Company Sales (2011)	=17210000*4.2%
	722820
Company Sales (2011)	=14437919*5.8%
	837399.3

Change in units	=Company sales in 2011- Company Sales in 2010
	114579.3
Change due to change in Industry growth	=Company Sales in 2010*19.2%
	138781.4

There is net increase of 138781.4 units of sales due to industry growth.

Answer to Part (2)
Industry Sales (2011)	17630000
	14877637
Company Sales (2011)	=17210000*4.1%
	740460
Company Sales (2011)	=14437919*5.8%
	862903
Change in units	=Company sales in 2011- Company Sales in 2010
	122443
Change due to change in Market share	=(Industry Sales in 2011*5.8%)-(Industry Sales in 2011*4.1%)
	299710

Thus there is a decrease in 299710 units of sales due to market share decrease.
