Answer:
Option (d) is correct.
The interest that she will earn after 3 years is $ 26.32.
Step-by-step explanation:
Given : Brianna deposited $680 into a savings account that pays a simple annual interest rate of 1.29%.
We have to calculate the interest that she will earn after 3 years.
Using simple interest formula,
[tex]SI=P\times r\times t}[/tex]
Where, P is principal
r is rate of interest
t is time period.
For the given data,
P = $ 680
r = 1.29% = 0.0129
t = 3 years.
Substitute, we have,
[tex]SI=680\times 0.0129\times 3}[/tex]
Simplify, we have,
Simple interest = $ 26.32
Thus, The interest that she will earn after 3 years is $ 26.32
