Question 122671: My economic class is quite challenging. Here is a question regarding the CPI.
I(t) = - 0.2t2 + 3t = 200 , t = 0 and corresponds to the year of 1995 where as 0 ≤ t & ≤ 5
What would the CPI by at in 1996?
What’s the rate of change from 1995 – 96?
How’s the index changing in 1998?
Any help in answering these questions on the CPI would be greatly appreciated. Thank you so much in advance!

You can put this solution on YOUR website!
I(t) = - 0.2t2 + 3t = 200
Your posted formula is probably wrong---a typo?
