Answer:
14.31 years
Explanation:
In this question, we use the NPER formula that is shown on the attachment. Kindly find the attachment below:
Data provided in the question
Present value = $9,000
Future value = $14,800
PMT = $0
Rate of interest = 0.29% per month
The formula is shown below:
= NPER(Rate;PMT;-PV;FV;type)
The present value come in negative
So, after solving this, the NPER per month is 171.77
In years, it would be
= 171.77 ÷ 12 months
= 14.31 years
