Hey there! I'm happy to help!
If you make a deposit, you add money to your bank account, and if you withdraw, you take money out of it.
We have $185.36 and we put in some deposits. Let's do this below.
$185.36+$13.74+$58.27+$69.30=$326.67
Now, we do some withdrawals and take money out.
$326.67-$19.29-$28.19-$52.55=$80.64
Therefore, Cybil has $226.64 in digital money.
Have a wonderful day! :D
