you are trying to price two bonds that have the same maturity and par value but different coupon rates and different required rates of return. both bonds mature in 3 years and have par values of $1000. one bond has a coupon rate of 7% and a required rate of return of 7%. the other bond has a coupon rate of 5% and a required rate of return of 5%. what is the absolute value of the difference between the price of these two bonds?
