Answer:
8.38%
Explanation:
We use the RATE formula in this question which is presented on the attachment below:
Given that, Â
Present value = $1,139
Future value or Face value = $1,000 Â
PMT = 1,000 × 9.9% ÷ 2 = $49.50
NPER = 18 years × 2 = 36 years
The formula is shown below: Â
= Rate(NPER;PMT;-PV;FV;type) Â
The present value come in negative Â
So, after solving this, the coupon rate is
= 4.19% × 2
= 8.38%
