Answer:
6.60%
Step-by-step explanation:
We use the RATE formula that is shown in the attachment
Given that,
Present value = $=1,459.51
Assuming figure - Future value or Face value = $1,000
PMT = 1,000 × 11% ÷ 2 = $55
NPER = 18 years × 2 = 36 years
The formula is shown below:
= Rate(NPER;PMT;-PV;FV;type)
The present value come in negative
So, after solving this, the coupon rate is
= 3.30% × 2
= 6.60%
