finance hw help

I have 35 finance questions to be completed. Here is the first, and the rest to follow are similar:

Bond J is a 5 percent coupon bond. Bond K is a 13 percent coupon bond. Both bonds have 8 years to maturity, make semiannual payments, and have a YTM of 9 percent. If interest rates suddenly rise by 3 percent, the percentage change in price of Bonds J and K is [removed] percent and [removed] percent, respectively. (Negative amounts should be indicated by a minus sign. Do not include the percent signs (%). Round your answers to 2 decimal places. (e.g., 32.16))
