[Question]A casino table pays 3:2 if you get a blackjack with your first 2 cards. If you scored a blackjack and were paid $60, what was your original bet?
[Answer]The payout for blackjack is 3:2 or 3 / 2 = 1.5 times my bet. If my original bet was X then I won 1.5 * X my bet. Given that I was paid $60 we know $60 = 1.5X. X = $60 / 1.5. X = $40 was my original bet. The answer is 40.

[Question]Onum Lake has 25 more trout than Boast Pool.  There are 75 fish in Boast Pool. Riddle Pond has half as many fish as Onum Lake. What is the average number of fish in all three bodies of water?
