Answer 1

$307.5.

Step-by-step explanation:

We have been given that Elena's aunt bought her a $150 savings bond when she was born.When Elena is 20 years old, the bond will have earned 105% in interest.

To find bond's value after 20 years we will add 105% of 150 to 150.

`\text{Bond's value after 20 years}=150+((105)/(100)* 150)`

`\text{Bond's value after 20 years}=150+(1.05* 150)`

`\text{Bond's value after 20 years}=150+157.5`

`\text{Bond's value after 20 years}=307.5`

Therefore, the bond will be worth $307.5, when Elena will be 20 years old.
