Answer:
$4,711.50
Step-by-step explanation:
If the APY of a savings account = Â 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
