Holder Enterprises still wants to issue fifty 25-year bonds with $1,000 par value, but with a 7 percent semiannual coupon rate and each bond is priced to yield 11 percent semiannually, how much in total will Holder Enterprises now receive (ignoring issuance costs) when the fifty bonds are sold?

What is the percentage change in amount financed from part (a) to part (b)?
