Answer:
$9,000
Step-by-step explanation:
Last year, Raphael bought a bond for $10,000 that promises to pay him $900 per year
Interest rate = $900/$1000 * 100 = 9%
This year, he can buy a bond for $10,000 that promises to pay $1,000 per year.
Interest rate = 1,000/10000 * 100 = 10%
If Raphael wants to sell his old bond, he has to lower its price in order to compensate for rise in interest rate. The bond, which he would sell, should pay 10% interest PA
=>> 900/10% * 100 = $9,000
So, the bond price is likely to be $9,000
