Answer 1

determine the change in price from month to month, add them all up and divide by 3

Answer 2

or would you only do sept - june//2 ?

Answer 3

sept + june//2 maybe....dunno, its unclear to me what its asking for... and average chnage from month to month to month or the average change from june to sept...

Answer 4

they are asking for the monthly average rate of change in price between Ju nd and September

Answer 5

i mean june and september

Answer 6

if we just hit june and sept we get:

87+122//2

209/2 = $104.50 as the avergare rate of change; but that sounds odd....
---------------------------

122 - 87 = $35 is the difference between the 2 months, but that aint no average.....
----------------------------

looks like we have to add up all the changes and divide by the number of months..

Answer 7

87 -> 100 = +13
100 -> 95 = -5
95 -> 112 = +17

17+13-5 = 25/3 = $8 + $1/3 would be the avergare rate of change i think....
