Answer:
Option B will be the correct option.
Step-by-step explanation:
The given expression is [tex]1800\times (1.2)^{-t}[/tex]
We can rewrite the term as
[tex]1800\times (\frac{1}{1.2})^{t}[/tex]
[As we know [tex]x^{-1}=\frac{1}{x}[/tex]]
Now we will simplify the expression
= [tex]1800(\frac{10}{12})^{t}[/tex]
= [tex]1800(\frac{5}{6})^{t}[/tex]
Therefore, Option B will be the correct option.
