Answer 1

Answer:

  $1,630.08

Step-by-step explanation:

The value of an amount earning interest continuously compounded is given by the formula ...

  A = Pe^(rt)

The value of P can be found by dividing by its coefficient:

  P = A/(e^(rt)) = Ae^(-rt)

  P = $1700·e^(-0.014·3) ≈ 1630.0786

Terry placed $1,630.08 in the account.
