well do it
like
1960 - 1970
100(.30-.15)/.15 = 100% (it doubled :)
1970 - 1980
100(.50-.30)/.30 = 67%
etc
then add them all up and divide by the number of them (4)
Calculate the percent of change of the hamburgers price each decade, and use
your results to determine the average rate of change from 1960–2000.
1960 1970 1980 1990 2000
$0.15 $0.30 $0.50 $0.75 $0.89

I don't understand.
percent increase
= 100(new price - old price)/( old price)
= 100(new price - old price)/( old price)
So what's the result of the average rate change?
