Answer:
8.36%
Explanation:
To find out the coupon rate, first we have to determine the PMT which is shown in the attachment below:
Given that,
Present value = $958
Future value = $1,000
Rate of interest = 8.9%
NPER = 14 years
The formula is shown below:
= PMT(Rate;NPER;-PV;FV;type)
The present value come in negative
So, after solving this, the yearly payment is $83.64
Now the coupon rate is
= $83.64 ÷ $1,000
= 8.36%
