SOLUTION: Exponential Functions It is known that fourth of all aluminum cans distributed will be recycled each year. A company distributes 1,9000 cans. The number of cans still in use

Question 58309: Exponential Functions
It is known that fourth of all aluminum cans distributed will be recycled each year. A company distributes 1,9000 cans.
The number of cans still in use after time t, in years, is given by the following function.

N(t)=1900(1/4)^t
How many cans are still in use after 5 years?

This is not from a text book, I am taking an on-line class.
I have tried this several times and can not seem to figure it out.

Exponential Functions
It is known that fourth of all aluminum cans distributed will be recycled each year. A company distributes 1,9000 cans.
The number of cans still in use after time t, in years, is given by the following function.

N(t)=1900(1/4)^t
N(5)=1900(1/4)^(5)
N(5)=1900(1/1024)
N(5)=1.85546875
You can round it off to whatever your asked for. Please double check the formula you typed in, and the question to be sure I gave you what you really wanted.
Happy Calculating!!!
