A) The table would be as following:
B) As a function, the expression would be:
[tex]M(n)=2^n[/tex]
Where M(n) is the area coverede by the mold, in square feet, and n is the time in moths the mold has been growing on the wall
C) Now, we know that the mold has to cover 240 square feet
[tex]240=2^n[/tex]
Solving for n,
[tex]\begin{gathered} 240=2^n\rightarrow n=\log _2240 \\ \Rightarrow n=7.9 \end{gathered}[/tex]
we get that it would take the mold 7.9 months to cover the wall.
