Amy had $84.35 before the deposit.

$116.85 - $32.50 = $84.35

She started out yesterday with $84.35 in her bank account.

Step-by-step explanation:

She starts out with x dollars in her bank account: x

To this amount she added $32.50, reaching a total balance of $116.85:

x + $32.50 = $116.85

Solving this by subtracting $32.50 from both sides, we get x = $84.35.
