Answer:
9.08%
Explanation:
For computing the coupon rate first we have to determine the monthly payment by applying the PMT formula which is to be shown in the attachment
Given that
Present value = 949
Future value or Face value = $1,000
RATE = 9.8% ÷ 2 = $4.90
NPER = 12.5 years × 2 = 25 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 monthly payment is $45.42
Now the coupon rate is
= ($45.42 × 2) ÷ $1,000
= 9.08%
