ANSWER
$11.42
Step-by-step explanation
The equation for simple interest is,
Where P is the deposited amount, r is the interest rate, and t is the time in years. In this case, we have to find how much is the interest after 3 months, which is 1/4 of a year, so we have:
• P = 3805
,
• r = 1.2% = 0.012
,
• t = 1/4 year = 0.25 year
The interest earned is,
Hence, the interest Dayna will earn in 3 months is $11.42.
