If the apy of a savings account is 4.7%, and if the principal in the savings account is $4500 for an entire year, what will be the balance of the savings account after all the interest is paid for the year?

$4,711.50

Step-by-step explanation:

If the APY of a savings account =  4.7%

Principal amount = $4500

time = 1 year

We use the formula of simple interest

A = P ( 1+rt )

Where, A = maturity amount

            P = Principal amount  ( 4500 )

            r = Rate of interest   4.7/100  or  ( 0.047 )

            t = one year  ( 1 )

A =  4500 ( 1 + 0.047 × 1 )

A = 4500 ( 1.047 )

A = $4,711.50

The balance of the savings account is $4,711.50 after all the interest is paid for the year
