How can I get the answer with a (CASIO calculator or without a financial calculator)?

EXAMPLE: COST OF DEBT Suppose we have a bond issue currently outstanding that has 25 years left to maturity. -The coupon rate is 9%, and coupons are paid semiannually. The bond is currently selling for $908.72 per $1,000 bond. What is the cost of debt? N = 50; PMT = 45; FV = 1000; PV =-908.72; CPT I/Y = 5%; YTM = 5(2) = 10%
