Answer:
the price of Bond A will change by 4.21% and the price of Bond B will change by 7.36%.
Explanation:
Bonds A and B
current bond price $1,000
interest rate 7%
Bond A matures in 5 years, annual payments
Bond B matures in 10 years, annual payments
if market interest decreases to 6%
Bond A:
$1,000 / (1 + 6%)⁵ = $747.26
$70 x 4.2124 (annuity factor, 6%, 5 periods) = $294.87
market price = $1,042.13
% change = 4.21%
Bond B:
$1,000 / (1 + 6%)¹⁰ = $558.39
$70 x 7.3601 (annuity factor, 6%, 10 periods) = $515.21
market price = $1,073.60
% change = 7.36%
