Answer:
$875
Explanation:
Generally, the relationship can be expressed as interest rate = Coupon Payment / Face Value.
Initially a 7% market rate a investor gets 7% which gives a coupon payment of $70 because the face value of 1000.
Hence 70/1000 = 7%
Subsequently with the interest rate change, we can look for the bond price.
Substitute 8% for the interest rate and find the revised bond value which will fall as rate increases
$70/bond price = 8%
Then $70/ bond price = 0.08
0.08 x bond price = $70
bond price = $70 / 0.08 = $875
