I'm having a difficult time with the below 2 problems. Can you please help me. Thanks!

1. Oriole, Inc., has issued a three-year bond that pays a coupon rate of 9.8 percent. Coupon payments are made semiannually. Given the market rate of interest of 4.0 percent, what is the market value of the bond?(Round answer to 2 decimal places, e.g. 15.25.)
2. Briar Corp is issuing a 10-year bond with a coupon rate of 7 percent. The interest rate for similar bonds is currently 9 percent. Assuming annual payments, what is the present value of the bond? (Do not round intermediate computations. Round your final answer to the nearest dollar.)
