His $20 bills amount to 4 x $20 = $80. So the total amount of the $10 and $20 bills is $80 + $50 = $130. Hence, the remaining $5 bills amount to $150 - $130 = $20. This means that there are $20 / $5 = 4 $5 bills. There are also $50 / $10 = 5 $10 bills. Therefore, Samuel has 4 + 4 + 5 = 13 bills in his wallet.
The answer: 13
Reverse engineering the question: Samuel has $5, $10, and $20 bills which amount to $150 in his wallet. His $10-bills amount to $50, and he has 4 $20-bills. How many bills does Samuel have in his wallet?


Reasoning and answer: The clown cost 100 * 4 = $400. The bounce house cost 100 * 3 = $300 per hour. He rented it for 4 / 2 = 2 hours. So it cost 300 * 2 = $600. That means the total cost was 400 + 600 + 1000 = $2000.
The answer: 2000
