Answer:
6.81 %
Step-by-step explanation:
The Required Interest Rate (i) is the yield to maturity and this is calculated as :
Pv = - $1,020.50
pmt = $1,000 × 7% = $70
n = 20
p/yr = 1
Fv = $1,000.00
i = ?
Using a Financial Calculator to input the values as shown, the yield to maturity (i) is 6.8094 or 6.81 %.
