Answer :
Answer:
Price of a bond is:
= Present value of coupon payments + Present value of bond maturity value or Par
Coupon = 8% * 1,000
= $80
This is a constant payment so can be treated as an annuity.
a. Price of bond at 7% YTM.
= (80 * Present value interest factor of Annuity (PVIFA) 7%, 25 years) + 1,000 / (1 + 7%)²⁵
= (80 * 11.6536) + 184.249177
= $1,116.54
b. Price of bond at 10% YTM:
= (80 * PVIFA 10%, 25 years) + 1,000 / (1 + 10%)²⁵
= (80 * 9.0770) + 92.295998
= $818.46
c. Price of bond at 13% YTM.
= (80 * PVIFA 13%, 25 years) + 1,000 / (1 + 13%)²⁵
= (80 * 7.3300) + 47.10195
= $633.50
