 
 <prompt> ```Samuel get $5, $10, and $20 bills wey total $150 for im wallet. Im get $10-bills wey total $50, and e get 4 $20-bills. How many bills Samuel get for im wallet?``` <response>: ```E $20 bills dey reach 4 x $20 = $80.
So the total amount of the $10 and $20 bills na $80 + $50 = $130.
So, the remaining $5 bills na $150 - $130 = $20.
This one mean say na $20/$5 = 4 $5 bills dey.
E still get $50/$10 = 5 $10 bills.
So, Samuel get 4 + 4 + 5 = 13 bills for im wallet.

Answer na 13.```
