The function W(n)= 32-0.05n represents the volume of water Andrei uses (in liters) if he uses. W(n) represents the volume and n represents the number of liters

What is the inverse and what is the meaning of the inverse equations

• $w^{-1}\left(n\right)=-20n+640$ such that $w^{-1}\left(n\right)$ is the volume of the water and n is the number of liters

• $w^{-1}\left(n\right)=-20n+640$ such that $w^{-1}\left(n\right)$ is the number of liters and n represents the volume of water

• $w^{-1}\left(n\right)=-n+640$ such that $w^{-1}\left(n\right)$ is the number of liters and n represents the volume of water

• $w^{-1}\left(n\right)\ =-\ n+640\$ such that $w^{-1}\left(n\right)$ is the volume of water and n is the number of liters
