Marley owns a music store. The first week a new album was released, he sold 800 coples at his store. Each week after the release, the number of coples sold decreased by $ 11 \% $.
Select all the functions that can be used to find the number of coples sold, $ (n) $, $ n $ weeks after the release.
$ f(n)=800(0.11)^{(n-1)} $
$ f(1)=11, f(n)=800 \cdot f(n-1) $, for $ n \geq 2 $
$ f(n)=800(0.89)^{(n-1)} $
$ f(1)=800, f(n)=0.11 \cdot f(n-1) $, for $ n \geq 2 $
$ f(n)=800 \cdot 0.89 n $
$ f(1)=800, f(n)=0.89 \cdot f(n-1) $, for $ n \geq 2 $
