Answer:

  $449.77

Step-by-step explanation:

The balance in account 1 can be found using the simple interest formula.

  A = P(1 +rt)

  A = $300(1 +0.045·3) = $340.50

The balance for account 2 can be found using the compound interest formula.

  A = P(1 +r)^t

  A = $100(1.03)^3 = $109.27

__

Darla's total balance will be ...

  $340.50 +109.27 = $449.77
