Question

25 = 100(0.95)^(n-1)

Answer 1

\[25 = 100(0.95)^{n-1}\]

Answer 2

\[.25=.95^{n-1}\]
\[n-1=\frac{\ln(.25)}{\ln(.95)}\] then a calculator

Answer 3

I don't understand...

What is

\[(0.95)^{n-1}\]

Answer 4

it is what you wrote

Answer 5

It's not 0.95n -0.95?

Answer 6

so for example if \(n=4\) you would have \((.95)^{4-1}=.95^3=0.857375\)

Answer 7

It's not

25 = 100(0.95n -0.95)

Answer 8

no not if the \(n-1\) is in the exponent

Answer 9

I am going to remake this question satelite.

Answer 10

ok
