Answered by GPT 3.5
First, we need to subtract the flat rate from the total monthly bill to find out how much of the bill is due to the per minute charge:

$38.44 - $3.99 = $34.45

Next, we need to divide the remaining amount by the per minute charge rate to find out how many minutes were used:

$34.45 ÷ $0.05 = 689 minutes

Therefore, Casey talked on her phone for 689 minutes.
