so 20600=100%
in 2009=1.2% change from 100%
not specific whether percent change is up or down so solve fo r1.2%
d
find 1.2% of 100
percent means parts out of 1001.2%=1.2/100=0.12/10=0.012/1=0.012
'of' means multiply
20600 times 0.012=276.2
the change is 276.2
20600-276.2=20352.8
20600+276.2=20847.2
you must round down since you can't sell 0.2 or 0.8 of a car
the sold either 20,352 or 20,847 cars in 2009
