And that's good on you, because the answer would've been c). Congratulations to your
$400 in cash
!

For your next deal, I've got an ATM. You'll start at $400 and I've filled it with banknotes: 10x $10, 10x $20, 10x $50, 10x $100 and 1x Zonk. You can take as many banknotes as you want - but if you hit the Zonk, you're out.
If you take the deal, please specify how many banknotes you want at first; at any point, you can request more banknotes or stop (you'll be offered another deal if you take at least one banknote).
