Answer:
R= 9.16%
Explanation:
Step 1. Given information.
Step 2. Formulas needed to solve the exercise.
The present value of r is considered taking into account the period of time of the exercise. In this case the period n=32 is because the amount is paid twice in a year, thus, n=16*2
Step 3. Calculation and Step 4. Solution.
Coupon = 10%*1000/2= 50
107%*1000 = 50*(1-1/(1+r/2)^32)/(r/2)+ 1000/(1+r/2)^32
R= 9.16%
