Answer: the realized rate of return = $105
Step-by-step explanation:
To calculate the the realized rate of return, first calculate the amount after six years with the premium which is an addition to the principal amount and then calculate the amount when the bond was bought for $1000.
amount at premium of $70( that is principal now is $1070) using compound interest formula: fv= p(1+r)∧n where p = principal=1070,
fv=amount required,r=rate of interest=7%,n=number of years =6,and
∧=raise to power.
fv=1070(1.07)∧6=1605
amount after investors bought it for $1000=1000(1.07)∧6= 1500
realized rate of return= 1605-1500= $105
