Question

Jenny has $1,200 in her savings account. If the bank pays 3% interest per year on savings, how much interest does she earn in one year? A.$36 B.$360 C.$3.60 D.$3600

Answer 1

Given:

Principal value = $1200

Rate of interest = 3% per year

To find:

The interest earned by Jenny in one year.

Solution:

Formula of interest:

`I=(P* r* t)/(100)`

Where, P is principal, r is rate of interest and t is time.

We have, P = 1200, r = 3, t=1. Putting these values, we get

`I=(1200* 3* 1)/(100)`

`I=(3600)/(100)`

`I=36`

The interest earned by Jenny in one year is $36.

Therefore, the correct option is A.
