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

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)
