Answer:
41 months
Step-by-step explanation:
For computing the time period we have to use the NPER formula i.e shown in the attachment
Given that,
Present value = $0
Future value = $1,400
Rate of interest = 16.80% ÷ 12 months = 1.4%
PMT = $45
The formula is shown below:
= NPER(Rate;PMT;PV;-FV;type)
The future value come in negative
So, after applying the above formula, the time period is 41 months
