Answer:
The change in the value of the bond is $0.90. In other words, the value of the bond has increased by $0.90 from yesterday to today.
Explanation:
We have Value of the bond = Quoted value / 100 * face value
So,
Yesterday value of the bond = 102.16/100 * 3,000 = $3064.8;
Today value of the bond = 102.19/100 * 3,000 = $3065.7.
=> Change in the value of the bond = Today value of the bond - Yesterday value of the bond = $3065.7 - $3064.8 = $0.90.
In other words, the value of the bond has increased by $0.9 from yesterday to today.
