Answer:
17.84 years
Explanation:
For this question, we use the NPER function that is presented on the excel spreadsheet. Kindly find the attachment below:
Given that,
Present value = $548
Future value = $1,000
Rate of interest = 13.20%
PMT = $1,000 Ć 6.5% = $65
The formula is shown below:
= NPER(Rate,PMT,-PV,FV,type)
The present value come in negative
So, after solving this, the number of years until these bonds mature is 17.84 years
