ANSWER

$11.42

EXPLANATION

The equation for simple interest is,

[tex]i=P\cdot r\cdot t[/tex]

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,

[tex]i=3805\cdot0.012\cdot0.25=11.415\approx11.42[/tex]

Hence, the interest Dayna will earn in 3 months is $11.42.
