hmm, in a restaurant you can get Schnitzel with french fries for ~ 10€ fries alone may cost something around 2€.
So we can ssume a Schnitzel alone has a value of ~8€
a Beer costs something around 1,5€ so...
3 Schnitzel ~ 24€
21 Beer ~ 31,5
EDIT but as you usually won't eat a Schnitzel without potatoes here, we can also assume, you've also bought the french fries...
and hey 3 Schnitzel ~ 30€ as equal as it gets...
Wow. Beer is about $5 a glass here. $3 if it's draft beer and happy hour.
A burger is anywhere between $3 and $8, depending on the quality. Fries are $2-$4 depending on the size.
A burger and basket of fries is around $10 or $12 with a quality burger and loads of fries.
Seems like with $100, he'd have 9 burger meals (tax sucks, lol). If he needs to go a week, that's not very good since he might want more than 1 meal a day.
I've got $240 to make it to Tuesday, though I have all my bills paid, a full tank of gas, and a fridge full of food. Not to mention that I paid out $576 to my credit card to avoid interest. Now I can add something back on my card. I'm thinking about a large ship :)
