Answer:
"1.64 years" is the appropriate solution.
Explanation:
Given:
After 1 year,
Received amount will be:
= $1,800
Now,
After 1 year,
Remaining amount will be:
= [tex]5000-1800[/tex]
= [tex]3200[/tex] ($)
In next year,
The required time to recover $3,200 will be:
= [tex]\frac{3200}{5000}[/tex]
= [tex]0.64[/tex]
hence,
The total payback period will be:
= [tex]1+0.64[/tex]
= [tex]1.64 \ years[/tex]
