find the value of a bond that pays a coupon of 4% annually, semiannually and has a time to maturity of 14 years.

Currently the market interest rate or expected yield (YTM - yield to maturity) is 5% annual APR (annual, compounded semi-annual). If the market rate drops to 4% APR, then what would the price be? If the market rate drops to 3% APR, then what would the price be? What behavior of the bond value can be observed when the market rate falls from 3% APR to 3% APR?
