Question 632680
Michael buys into a mutual fund to save for retirement, but does not add any money after his initial investment. His account balance is $2,700 after three years, $3,290 after five years; $4,030 after seven years; $5,440 after 10 years; and $8,950 after fifteen years. Perform an exponential regression on this data to complete the following items.
----
Paired-data: (3,2700) ; (5,3290) ; (7,4030) ; (10,5440); (15,8950) 
Running an exponential regression on a TI-84 I get:

y = 2000*1.105^x
---------------------------
1. What was the amount of Michael's initial investment (to the nearest dollar)? 
Ans: $2000
------------------------
2. What (to the nearest tenth of a percent) is his annual rate of return.
Ans: 10.5%

3. What is the projected account balance at Michael's retirement, 35 years after his initial investment (to the nearest dollar)?
f(35) = $65,873
