A person's retirement account of $30,000 earns 4% each year. Which value would represent the base of the exponential function that models this situation?

1) 30,000

2) 1.04

3) 1.4

4) 4

Well, your probably gonna not go with 30,000 because it stands out like a sore thumb. and 4% is = to. 04 So that would be my likely guestimation. 1.04 is probably the answer. in high school you would do 30,000 (1+.04/1

) ^1*1

and if you were to simplify

30,000 (1+.04)

or

30,000 (1.04)

So i would say 1.04 is the answer
