the average rate of change is
change in cost/ number of years
so take the cost in 2000- cost in 1960
and divide by number of years bewtween 1960 and 2000
So I would not have to find you the percent of change between each one like the change between 1960 and 1970?
It doesn't ask for % change
so take the actual cost

Sorry I didnt give you the question :P
it is this:
Calculate the percent of change of the item's price each decade, and use your results to determine the average rate of change from 1960–2000.
My real problem was with 1970-1980
They are .09 cents apart then I did this|dw:1450124465983:dw|
ok - sorry - haven' t ime to do this now - maybe best to post the actual question first next time
yeah - it says find the % change EACH decade
first on 1970 -1960 = (6-4)/4 *100% = 50 %
do the rest
