I need to learn how to solve these types of questions using a BA financial calculator.

1)Ghost Rider Corporation has bonds on the market with 12 years to maturity, a YTM of 5.8 percent, and a current price of $956. What must the coupon rate be on the companys bonds?

2)Great Wall Pizzeria issued 7-year bonds one year ago at a coupon rate of 6.5 percent. If the YTM on these bonds is 8.6 percent, what is the current bond price?

3)Sopranos Spaghetti Factory issued 24-year bonds two years ago at a coupon rate of 7.60 percent. If these bonds currently sell for 86.25 percent of par value, what is the YTM?

4)Fooling Company has a 12.6 percent callable bond outstanding on the market with 25 years to maturity, call protection for the next 10 years, and a call premium of $50. What is the yield to call (YTC) for this bond if the current price is 108 percent of par value?
