Answer:
7.8%
Step-by-step explanation:
For computing the coupon rate first we have to determine the PMT by using the PMT formula which is shown in the attachment below:
Given that,
Present value = $969
Future value or Face value = $1,000
RATE =8.1%
NPER = 17 years
The formula is shown below:
= PMT(RATE;NPER;-PV;FV;type)
The present value come in negative
So, after applying the above formula, the PMT is $77.58
Now the coupon rate is
= $77.58 รท $1,000
= 7.8%
