AutoMessage: While I'm not here try to solve this... There were three guys at a bar, and they had to pay $30, so they paid $10 each.. so $10+$10+$10 = $30 But hey... there was a mistake, they had to pay $25 instead of $30 actually, so they got five $1 coins back and they leave a $2 tip. So here's the thing: Everyone payed $10, minus they $1 they got back, it's $9 each, so $9x3 = $27 + the $2 tip it's = $29, but in fact they payed $30... so where's the missing $1? Solve it and you might just get that $1

$30 - ($25 divide by 3 person)= there's the $1
