Answer 1

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

Answer 2

So I would not have to find you the percent of change between each one like the change between 1960 and 1970?

Answer 3

It doesn't ask for % change

so take the actual cost

Answer 4

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.

Answer 5

My real problem was with 1970-1980
They are .09 cents apart then I did this

Answer 6

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
